Resumen
Over the last few decades, considerable research efforts have been directed toward the development of effective chemical syntheses of camptothecin and its analogs. The last comprehensive review of this area was published in 2003 and many effective new methods have since been reported for the stereoselective synthesis of the camptothecin alkaloids. In this account, we have summarized most of the novel synthetic approaches developed for the synthesis of camptothecins during the last decade. We have focused on strategies for the construction of the pentacyclic ring system and the different methods used to install the chiral quaternary center on the E ring of camptothecin.1 Introduction2 Synthesis of Racemic Camptothecins3 Enantioselective Synthesis of Camptothecins3.1 Sharpless Asymmetric Dihydroxylation3.2 Catalytic Asymmetric Cyanosilylation3.3 Auxiliary-Induced Asymmetric Carbonyl Addition3.4 Catalytic Asymmetric Ethylation3.5 Asymmetric Hydroxylation4 Conclusion

Resumen
Asymmetric syntheses of six-membered ring heterocycles are important research targets not only in synthetic organic chemistry but also in pharmaceuticals. The [3+3]-cycloaddition methodology is a complementary strategy to [4+2] cycloaddition for the synthesis of heterocyclic compounds. Recent progress in [3+3]-cycloaddition processes provide powerful asymmetric methodologies for the construction of six-membered ring heterocycles with one to three heteroatoms in the ring. In this account, synthetic efforts during the past five years toward the synthesis of enantioenriched six-membered ring heterocycles through asymmetric [3+3] cycloaddition are reported. Asymmetric organocatalysis uses chiral amines, thioureas, phosphoric acids, or NHC catalysis to achieve high enantiocontrol. Transition-metal catalysts used as chiral Lewis acids to activate a dipolar species is an alternative approach. The most recent advance, chiral transition-metal-catalyzed reactions of enoldiazo compounds, has contributed toward the versatile and highly selective synthesis of six-membered heterocyclic compounds.1 Introduction2 Asymmetric Formal [3+3]-Cycloaddition Reactions by Organo­catalysis2.1 By Amino-Catalysis2.2 By N-Heterocyclic Carbenes2.3 By Bifunctional Tertiary Amine-thioureas2.4 By Chiral Phosphoric Acids3 Asymmetric Formal [3+3]-Cycloaddition Reactions by Transition-Metal Catalysis3.1 Copper Catalysis3.2 Other Transition-Metal Catalysis4 Asymmetric [3+3]-Cycloaddition Reactions of Enoldiazo Compounds4.1 Asymmetric [3+3]-Cycloaddition Reactions of Nitrones with Electrophilic Metallo-enolcarbene Intermediates4.2 Dearomatization in Asymmetric [3+3]-Cycloaddition Reactions of Enoldiazoacetates4.3 Asymmetric Stepwise [3+3]-Cycloaddition Reaction of Enoldiazoacetates with Hydrazones5 Summary and Outlook

Resumen
While the exploitation of the Sharpless asymmetric dihydroxylation as the source of chirality in the synthesis of acyclic molecules and saturated heterocycles has been tremendous, its synthetic utility toward chiral benzo-annulated heterocycles is relatively limited. Thus, in the search for wider applications of Sharpless asymmetric dihydroxylation-derived diols for the synthesis of benzo-annulated heterocycles, we report herein our studies in the asymmetric synthesis of (R)-1-((R)-6-fluorochroman-2-yl)ethane-1,2-diol, (R)-1-((S)-6-fluorochroman-2-yl)ethane-1,2-diol and (S)-6-fluoro-2-((R)-oxiran-2-yl)chroman, which have been used as late-stage intermediates for the asymmetric synthesis of the antihypertensive drug (S,R,R,R)-nebivolol. Noteworthy is that a large number of racemic and asymmetric syntheses of nebivolol and their intermediates have been described in the literature, however, the Sharpless asymmetric dihydroxylation has never been employed as the sole source of chirality for this purpose.

Resumen
AbstractIn the past decade, asymmetric synthesis of chiral ligands containing quinoline motifs, a family of natural products displaying a broad range of structural diversity and their metal complexes, have become the most significant methodology for the generation of enantiomerically pure compounds of biological and pharmaceutical interest. This review provides comprehensive insight on the plethora of nitrogen-based chiral ligands containing quinoline motifs and organocatalysts used in asymmetric synthesis. However, it is confined to the synthesis of quinoline-based chiral ligands and metal complexes, and their applications in asymmetric synthesis as homogeneous and heterogeneous catalysts.1 Introduction2 Synthesis of Chiral Ligands Containing Quinoline Motifs2.1 Synthesis of Schiff Base Type Chiral Ligands2.2 Synthesis of Oxazolinyl-Type Chiral Ligands2.3 Synthesis of Chiral N,N-Type Ligands2.4 Synthesis of Amine-Based Chiral Ligands2.5 Synthesis of P,N-Type Chiral Ligands2.6 Synthesis of Chiral N-Oxide and Nitrogen Ligands3 Homogeneous Catalytic Asymmetric Reactions3.1 Asymmetric Carbon–Carbon Bond Formation Reactions3.2 Asymmetric Allylic Reactions3.3 Asymmetric Cycloadditions3.4 Asymmetric Carbene Insertions3.5 Asymmetric Pinacol Couplings3.6 Asymmetric Pudovik Reactions3.7 Asymmetric Strecker Reactions4 Heterogeneous Catalytic Asymmetric Reactions4.1 Asymmetric Cyclopropanation of Olefins4.2 Asymmetric Heck Reactions4.3 Asymmetric Hydrogenations4.4 Asymmetric Hydroformylation of Styrene4.5 Asymmetric Dialkoxylation of 2-Propenylphenols4.6 Asymmetric Cascade Cyclizations4.7 Asymmetric Allylic Alkylations4.8 Asymmetric Alkylation of β-Keto Esters4.9 Asymmetric C–H Bond Arylation Reactions4.10 Intramolecular Aerobic Oxidative Amination of Alkenes4.11 Asymmetric Oxidative Hydroboration of Alkenes5 Conclusions

Resumen
One possible way of achieving absolute asymmetric synthesis is by "freezing" the chirality of a molecule by crystaUisation. This work is a study of the synthesis of :ertain imides which have potential for axial chirality and are likely to undergo spontaneous resolution on crystallisation. The synthesis starts from achiral compounds and therefore, if it does yield chiral crystals by spontaneous resolution, it can be classified as absolute asymmetric synthesis.

Resumen
It has been demonstrated that bakers' yeast reduction of 1-tert-butyl-2-methyl 3-oxo-piperidine-1,2-dicarboxylate gives (2R, 3S), 1-tert-butyl-2-methyl 3-hydroxy-piperidine-1,2-dicarboxylate in 80% chemical yield with >99% d.e. and >97% e.e. Also bakers' yeast reduction of 1-tert-butyl-3-ethyl 4-oxo-piperidine-1,3-dicarboxylate gives (3R, 4S), 1-tert-butyl-3-ethyl4-hydroxy-piperidine-1,3-dicarboxylate in 74% chemical yield with >99% d.e. and >93% e.e. The optical purity and absolute configurations of the hydroxy-ester derivatives were determined by conversion into the corresponding chiral bis-tosylate derivatives of 2- and 3-piperidinemethanol respectively. It has also been shown that bakers' yeast reduction of 1-tert-butyl-4-methyl 3-oxo-piperidine-1,4-dicarboxylate gives (3R, 4R)-1-tert-butyl-4-methyl 3-hydroxypiperidine-dicarboxylate in 81% chemical yield with >99% d.e. and 87% e.e. The optical purity and absolute configuration of the hydroxy-ester derivative were determined by utilisation of the compound in the total synthesis of (R)-3-quinuclidinol via chain elongation at C-4 of the piperidine followed by cyclisation to produce the bicyclic structure. Further work is reported on the diastereoselective synthesis of polyhydroxylated indolizidine alkaloids. 1-Acetoxy-2-hydroxy-3-(hydroxymethyl)-indolizidine has been synthesised as a single diastereomer from 2-piperidinemethanol via attack of an amine onto an epoxide functionality thus producing the bicyclic system.

Resumen
Broad-Spectrum Chemokine Inhibitors (BSCIs) are a novel type of antiinflammatory drug, discovered by Fox and colleagues. We have shown that the syntheses of C-substituted γ-thialactams are possible via a modular approach starting from the simple amino acid cystine. These compounds are a new class of GPCR ligand, showing BSCI activity comparable to their non-sulfur counterparts. Initial migratory data suggests that these lactams are inhibitors of leukocyte migration and comparable to the analogous BSCI lactams at μM concentrations, with decreased activity at the nM scale. Efforts have been made to the synthesis of substituted piperidinones, as well as employing Jocic-Reeve-Corey-Link chemistry to the general synthesis of lactams, ultimately looking to the synthesis of C-substituted lactams. Attempting to utilise trichloromethyl carbinol chemistry for these purposes has led to the synthesis of stereochemically-pure heterocycles containing up to 3 stereocentres. α- Trichloromethyl carbinols and asymmetric transfer hydrogenation chemistry are used from simple starting materials. Developments of this type of chemistry will undoubtedly lay the foundations to produce further non-racemic substituted heterocycles which will be important both synthetically and biologically.

Resumen
The stereoselectivity of TiCI₄-catalysed Mukaiyama reactions of a camphor acetal-derived chiral silyl enol ether with a range of substituted aromatic aldehydes has been examined. The enantiomeric excess in each of the resulting ß-hydroxy ketones, determined by ¹H NMR spectroscopy using the lanthanide chiral shift reagent Pr(Etcf₃), ranged between 9 and 13%. The stereo-directing potential of the camphor acetal as a chiral auxiliary in the α-benzylation of carboxylate esters has been studied; the acids were chosen to illustrate substituent effects on asymmetric induction. The observed diastereoselectivity increased with increasing steric bulk of the ester group and α-benzylation of the tert-butylacetate derivative proceeded with 48% diastereoselectivity. It is proposed that the enolate adopts an endo-s-trans conformation in the transition state and preferential attack by the electrophile at the somewhat less hindered Si-face is supported by both the optical rotation data and computer modelling studies. Reductive cleavage and hydrolysis of one of the benzylated esters furnished known products from whose optical rotation the configuration of the major diastereomer was established. In order to improve the steric advantage of Si-facial attack, methods of increasing the steric bulk of the blocking group were explored. A novel 2,2-propylenedioxy hydroxycamphor acetal and its 3,3-propylenedioxy analogue were prepared. Selected carboxylate esters of these propylenedioxy acetals were subjected to α-benzylation and the 2,2-(propylenedioxy)-3-exo-tert-butylacetate derivative showed a diastereoselectivity of 57% during a-benzylation. Hydrolysis of the abenzylated phenylacetate analogue offered the known 2,3-diphenylpropanoic acid whose optical rotation indicated the preferred configuration at the new chiral centre to be (R), a result which is consistent with the proposed approach of the electrophile to the less hindered Re-face of theendo-s-trans enolate moiety and reflects an inversion of the configurational bias observed with 2-v exo-carboxylate analogues. Attempts to prepare the monocatechol acetal of the hydroxy camphor derivative although unsuccessful, led to the isolation of two novel dibornyl ethers whose structures were established by 1- and 2-D NMR spectroscopy. A study of novel applications of camphor-derived auxiliaries in the asymmetric synthesis of α-amino acids has been initiated. The several approaches tried led to the preparation of three novel dural glycine derivatives in good yield

Resumen
The synthesis of useful chiral skeletons from simple achiral starting materials is always the dream of organic chemists. In the past decades, organocatalysis has been rapidly developed and has become one of the most important methods in asymmetric catalysis. The aim of this thesis is to develop asymmetric methods for the construction of useful chiral skeletons based on organocatalytic chemistry. Many natural products and biologically important compounds contain the hydrogenated dibenzofuran (Figure 1) as a common sub-structure. In the first part of this thesis, the first amine-catalysed asymmetric synthesis of a dihydrodibenzofuran species from bisenal substrates has been demonstrated. After a systematic screening of various reaction parameters, the optimal conditions have been found to be as follows: 0.1 M of substrate in solution with toluene with 0.2 equiv of (S)-di(2-naphthyl)pyrrolinol TMS ether (C2.8) and 0.2 equiv of 2-nitrobenzoic acid at 50 ℃ for 7 h under an argon atmosphere (Scheme 1). The first step product, an aldehyde, can be reduced in one pot to an alcohol by NaBH4. This two-step protocol gives exclusive cis selectivity. Many chiral cis-dihydrodibenzofuran species have been synthesized from the corresponding bisenal substrates in moderate to good yield with good to excellent ee (Scheme 1). The resulting cis-dihydrodibenzofuran species have promising synthetic applications. As shown in Scheme 2, the less hindered face of the newly formed C ring is more reactive and highly regioselective functionalizations of the C ring have been achieved. In the second part of this thesis, the first asymmetric aziridination of trans-α-nitroalkenes via a phase-transfer catalysis strategy has been systematically studied. The chiral phase-transfer catalysts screened are derivatives of the cinchona alkaloids. The new cinchonidine-derived phase-transfer catalyst CD17 has been found to be optimal for the aziridination (Figure 2). Addition of a small amount of water is crucial to achieve complete conversion of the reaction. Both trans-1-nitro-2-arylalkenes and trans-1-nitro-2-alkylalkenes are suitable substrates (Scheme 3). The reaction can be run on the gram-scale without significant loss of efficiency and ee. Mechanistic studies have revealed that the aziridination proceeds through an aza-Michael addition followed by an intramolecular SN 2 type three-membered ring formation (Scheme 4).

Resumen
Prostaglandins (PGs) are medicinally interesting because of the wide variety of roles they play in the body. PGs are ubiquitous and can be found in the reproductive system, the nervous system, the cardiovascular system, and the immune system. Accordingly, PGs are an important therapeutic target for pharmaceutical companies, and an efficient synthesis is highly desirable. Past research indicates that an approach to prostaglandins via a chiral acetylenic ester or amide provides a promising method for control of C-15 geometry. This project seeks to validate a key stereospecific reduction of an enantiomerically pure cyclopentenone intermediate. This is in turn available from a chiral acetylenic ester or amide via a formal [3+2] cycloaddition step. Several methods have been investigated for asymmetric synthesis of the requisite chiral acetylenic acid derivative including asymmetric conjugate addition, CBS-oxazaborolidine reduction of a ketone, and the separation of diastereomers of a chiral amide. With the optically pure cyclopentenone in hand, we will investigate hydroxyl directed conjugate reduction of the cyclopentenone double bond.

Resumen
This thesis is concerned with the asymmetric synthesis of cyclopropyl derivatives via the use of chiral iron acyl complexes of the type (η5-C5H5)Fe(CO)(PPh3)(COCH=CR'R), Chapter 1 reviews previous routes to optically active cyclopropyl derivatives and reviews the use of the chiral auxiliary (η5-C5H5)Fe(CO)(PPh3) for asymmetric synthesis. Chapter 2 describes the synthesis of the complexes (η5-C5H5)Fe(CO)(PPh3)(COCH=CRR') and presents a conformational analysis of the α, β-unsaturated acyl ligand. Chapter 3 describes the diastereoselective synthesis of cis- substituted cyclopropyl complexes via the reaction of Z-α, β-unsaturated iron acyl complexes with electrophilic alkylidene species. Decomplexation, to give the corresponding cyclopropyl esters, occurred without epimerisation of the cyclopropane ring. By the use of homochiral iron acyl complexes the enantioselective synthesis of cyclopropyl derivatives was achieved. Section A describes methylene addition and Section B isopropylidene addition reactions. Section C describes attempts to synthesise pyrethroid insecticide precursors which occurred with good diastereoselectivity but poor regioselectivity. Section D describes electrophilic ethylidene addition reactions in which the chiral auxiliary exerts good stereochemical control over three new chiral centres. Chapter 4 describes the diastereoselective synthesis of trans- substituted cyclopropyl complexes via the reaction of E-α, β-unsaturated iron acyl complexes with nucleophilic alkylidene transfer reagents. Section A describes methylene transfer reagents. Whilst α-lithiosulphides and α-lithiosulphoxides were of limited use, iodomethyllithium (generated in situ) resulted in highly diastereoselective syntheses of the cyclopropyl complexes. Decomplexation, to give the corresponding cyclopropyl esters, occurred without epimerisation of the cyclopropane ring. By the use of homochiral iron acyl complexes the enantioselective synthesis of cyclopropyl derivatives was achieved. Section B describes the generation of 1-iodoethyllithium and 1-iodobutyllithium and their reactions as nucleophilic alkylidene transfer reagents. The stereo- chemistry at two of the new chiral centres is controlled by the iron chiral auxiliary, whilst that at a third is controlled by a number of factors.
