Texto completoChapter 2 of this thesis describes a new copper-catalyzed multicomponent synthesis of alpha-substituted amides. This reaction was developed based upon previous work in this laboratory, which showed that palladium catalysts were competent in Stille-type cross-coupling of imines, acid chlorides, and organostannanes. While providing a mild method of generating the amide products, a more general procedure able to incorporate a wider range of organostannanes was sought. This chapter details the development of a copper-catalyzed protocol, which, as well as performing the cross-coupling under mild reaction conditions, proceeds with a diverse range of aryl-, heteroaryl-, and vinyl-substituted organostannanes and employs an inexpensive and readily available catalyst. Through this system, control over regioselectivity of addition to alpha,beta-unsaturated imines is also possible.
Chapter 3 demonstrates that, in addition to organostannanes, other substrates are viable in copper-catalyzed cross-coupling with imines and acid chlorides. Herein, the coupling of terminal alkynes with imines and acid chlorides is described, leading to an efficient synthesis of tertiary propargylamides directly from simple starting materials. This synthesis incorporates a wide variety of substituted imines, acid chlorides/chloroformates, and terminal alkynes, providing a rapid synthesis of these useful building blocks (reaction completion in only 15 minutes). In addition, the process is shown to work with aza-aromatic heterocycles, such as pyridine, where the alkynylation occurs exclusively at the 2-position.
Chapter 4 describes the utility of these rapid multicomponent reactions, where the products are directly converted into oxazole heterocycles. Copper-catalyzed- and zinc-catalyzed protocols are developed for the synthesis of secondary propargylamides from silyl-imines, acid chlorides, and terminal alkynes. The secondary propargylamide products are then, in a one pot sequence, transformed into trisubstituted oxazoles.
Chapter 5 describes the development of an atom-economical, non-toxic alternative to the organotin coupling described in Chapter 2. This involves the use of tri- and tetraorgano-indium reagents, which can transfer all of their organic groups in a copper-catalyzed coupling with imines and acid chlorides. This reaction shows good functional group compatibility and further expands the scope of alpha-substituted amides and N-protected amines that can be synthesized through mild copper catalysis.
Chapter 6 explores the enantioselective alkynylation of nitrogen-containing heterocycles. As described in Chapter 3, heterocycles such as pyridine can undergo copper-catalyzed 1,2-addition with terminal alkynes upon activation by chloroformates. As this process generates a stereocenter, it is possible to introduce enantio-control into the reactions by using a chiral copper catalyst. With ligands from the PINAP series, enantioselectivities of up to 84% can be induced in the coupling of nitrogen-containing heterocycles (e.g., quinoline), chloroformates, and terminal alkynes. This provides a mild and simple synthesis of chiral 2-alkynyl-1,2-dihydroquinolines directly from simple starting materials.

Texto completoIn this thesis, a design of new Re, Ga and In coordination compounds is proposed. The ligands semicarbazones, thiosemicarbazones and imines could be prepared from 3-(chloromethyl)-2-hydroxy-5-methylbenzaldehyde as initial material. This aldehyde is not available commercially, but it could be obtained in three steps from 2,6-bis(hydroxymethyl)-4-methylphenol in 76 % yield. Using N-alkylation and condensation reactions, the ligands were prepared in 60 to 75 % yields. A series of tridentate, pentadentate and hexadentate ligands were designed to different metal ions, showing the versatility of the chloride/aldehyde reagent. Unfortunately, the ReV complexes were not fully characterized as stable complexes. Semi and thiosemicarbazones, H4bsc and H4btsc, formed GaIII and InIII complexes, as hexadentate ligands in good yields (60-90 %). The hexacoordinated bis(semicarbazone) Ga complex, [Ga(HbscPh)], was obtained as a zwitterion neutral compound and as a cationic form of a nitrate salt, from [Ga(acac)3] and [Ga(NO3)3], respectively. The same ligand, H4bscPh, reacted with [In(acac)3], resulting a zwitterion neutral In complex, [In(HbscPh)], but using [InCl3] a mixture of products was observed. The radioactive congener complex [67Ga(HbscPh)] was obtained in quantitative yields from 67GaCl3 (15 min, at room temperature) therefore the complex presented considerable stability in in vitro (PBS, apo-tranferrin, human blood serum assays) and in vivo (blood and urine after the administration to normal mice). The biodistribuition assays resulted in liver and instestines uptake, which could be related with the lipophilicity of the complex (log P 1,44). In experimental conditions, bis(thiossemicarbazones) 67Ga radiocomplexes were not obtained in reasonable yield and purity. However the radiocomplex [111In(HbtscMeMe)] was obtained in quantitative yields and in high purity (15 min, at room temperature), justifying stability assays. The 111In complex was less stable than 67Ga complex, though the similar uptake. The both complexes are lipophilic, but [111In(HbtscMeMe)] (log P 2,66) presented better blood clearance. The results were promising and new studies toward structural optimizing are proposed, in this way, water soluble complexes and specific agents (coupling to biomolecule) could be prepared.

Texto completoThe main goal of the PhD research was the development of novel homogeneous catalysts for copolymerization of ethylene with polar vinyl monomers, such as acrylic esters, in order to obtain functionalized polyolefins with a controlled content of the inserted polar monomer. The project focused on the synthesis and characterization of palladium(II) complexes with novel non symmetric nitrogen-donor ligands of increasing complexity, and belonging either to the class of alpha-diimines or to the group of the pyridylimines. The catalytic behaviour of the synthesized palladium(II) complexes in the ethylene/methyl acrylate copolymerization was investigated in detail. Some of the catalysts were also applied to other reactions such as the CO/vinyl arene copolymerization and the bis-alkoxycarbonylation of alkenes, demonstrating the versatility of palladium catalysts with N-donor ligands.

Texto completoFor the last years Environmental issues have deserved featured in the National and International media. Chemistry has had great participation on currently days with countless products which are fundamental to humanity. Its presence can be detached from various fuels to the most complex drugs.The organic synthesis reactions should be guided by more sustainable new practices. In this field, the Green Chemistry concept or (Química Verde) strategy which aims to develop methodology and and/or processes which use and generate the minimum quality of toxic inflammable material. With the purpose of contribute to green chemistry, we studied the synthesis of imines which consisted of the first stage of the process of amination, free of organic solvents and have yields higher than 95%; gem-dichloroaziridine were prepared from the imines insertion dichlorocarbene in a minimum of organic solvent conditions, using as catalyst KF/Al2O3 and yields higher than 98%. The gem-dichloroaziridines were converted to amides by hydrolysis in absence of solvent and yields higher than 98.0%. Within the concept of Green Chemistry were prepared six imines: N-benzyl- phenylmethanimine, N-phenyl-2- furylmethanimine, N-phenyl- phenylmethanimine, N-phenyl-(4-methoxyphenyl)methanimine, N-benzyl-(4-methoxyphenyl)metha-nimine,N-(2-furylmethyl)-2-furylmethanimine; two gem-dichloroaziridinas: 2,2-dichloro-1,3-diphenyla-ziridine and 1-benzyl-2,2-dichloro-3-phenylaziridine and two amides: chlorophenylacetanilide and N-benzyl-chloro-phenylacetamide.

Texto completoTriple bonds are among the most important moieties in organic chemistry because of their great synthetic potential. Among all classes of alkynes, those being directly substituted by a nitrogen atom have attracted the attention of many groups. A family belonging to this class, the ynimines has been little studied because of difficulties encountered for their preparation. In this context, and in continuity with previous work from our laboratory, we have been interested in the development of new methods of synthesis of these compounds. We have developed efficient and mild methods for the preparation of ynimines based on a copper-catalyzed alkynylation of imines with terminal alkynes and on a direct oxidative alkynylation of imines with alkynylcopper reagents. These building blocks were shown to be especially suitable precursors for the synthesis of azadienes, quaternary nitriles, unsaturated nitriles, cetenimines and α,β-unsaturated amides. Indoles by intramolecular carbolithiation or carbocupration of ynamides. These new reactions allow for a straightforward and original entry to these various heterocyclic systems, which could be highlighted by a formal synthesis of a bioactive compound: Sarizotan. All together, this work should contribute to further expand the synthetic utility of ynamides as well as intramolecular carbometallation reactions in organic synthesis

Texto completoThis thesis deals with the synthesis and the reactivity of a large variety of acetylenic ω-ketoesters both in racemic and optically active series. First of all, we have performed new synthetic approaches, which can be modulated easily, to afford this kind of compounds. Then, we have focused our attention on the intramolecular reactivity of the acetylenic ω-ketoesters, toward different bases and in particular TBAF and t-BuOK. We have shown that depending on the base which is used in the reaction, we are able, using new cascade reactions, to have direct access to spiranic derivatives, to allenic esters, to oxacycles or to tricyclic derivatives. We have also tried to rationalize our results by means of semi-empirical MO calculations. This methodology was finally used to develop novel synthetic approaches for the preparation of sesquiterpenic naturel bioactive products belonging to the Iphionane family
