-hydroxylated products which are easily racemized, protection was directly adjusted via acetylation so as to prevent this possibility. Resulting enantiomerically enriched products were subjected to Upjohn Dihydroxylation to obtain cyclitol precursors and following Luche Reduction of ketone was adjusted so as to obtain corresponding cyclitols. In addition with such synthetic design, firstly dimethyl cyclopent-3-ene-1,1-dicarboxylate was obtained so as to reach in former manner 3-cyclopentene-1,1-dicarboxylic acid, and in latter manner cyclopent-3-enecarboxylic acid. Resulting compound was converted to 6-iodo-2-oxa-bicyclo[2.2.1]heptan-3-one and followingly to the target nucleoside precursor which is 2-oxa-bicyclo[2.2.1]hept-5-en-3-one.

Pełny tekst źródłaIn this work we performed a deeper study for obtaining (S)-2-tert-butylamide-4-(3-picolyl)piperazine by opening (S)-2-tert-butylcarboxamide-N-p-tosylaziridine followed by cyclization, in 78% yield, with diphenylvinylsulfonium trifluoromethanesulfonate. The aziridine were prepared by a cyclization process in phase transfer conditions, starting from L-serine, a low cost amino acid. This synthetic route yielded a material which has the same S piperazinic fragment stereochemistry used in the synthesis of Indinavir, and may constitute an alternative route for obtaining this drug.

Pełny tekst źródłaThe work incorporated in this thesis is mainly focused on various single source metal precursors like metal thiolates and metal dithiocarbamate complexes. Herein, several simple and general methods have been developed for the synthesis of various such single source metal precursors, which comprising the main two constituents of metal chalcogenide nanocrystals (NCs), namely, the tiny inorganic metal chalcogenide complex as core and an organic molecule as shell. Specially, both binary metal thiolates and bimetallic (ternary) thiolates have been prepared and both of them turned out to be excellent precursors for the synthesis of metal sulfide/selenide NCs. The methods used to prepare metal chalcogenide NCs included a direct-heating (solvo-thermal decomposition) method or solid state grinding method. First, the large scale synthesis of various 2D molecular precursors like metal thiolates and metal dithiocarbamate complexes (M-C8DTCA) have been developed and studied their thermal decomposition to metal sulfide NCs via solution based methods. We observed that some of the metal thiolates like Pb-thiolate requires very high temperature to decompose into PbS resulting in particles bigger than their Bohr exciton radius and hence displayed poor optical properties. In the next, to reduce the decomposition temperature an active sulfur precursor called octyl ammonium octyldithiocarbamate (C8DTCA) has been utilized for the synthesis of various metal sulfide NCs (including most challenging PbS NCs, with tunable optical properties) by solution based method (hot injection) or solid state grinding method. We also show that the size of the nanocrystals could be controlled by changing the reaction temperature or metal: chalcogenide precursor ratio. Interestingly, we have also been successful in establishing that these newly developed solid state grinding methods are scalable without compromising their structural and optical properties. The binary or ternary materials synthesized by these solid state routes could be re-dispersed as desired in non-polar organic solvents allowing them to be solution processible. The optical properties of the metal chalcogenide nanocrystals could further be improved by post synthetic surface passivation.

Pełny tekst źródłaGreen et al. attempted to synthesize linear naphthopyranquinones from a naphthyl dioxolane using a TiCl4 as a catalyst. They managed to synthesise an angular naphthopyran as well as a linear naphthopyran in low yield. They showed that reducing the steric strain at position 1 of the naphthyl dioxolane afforded a low percentage yield of the linear naphthopyran plus an angular one. This thesis describes the synthesis of linear naphthopyrans with an improved percentage yield using TiCl4 as a catalyst. This was achieved by placing a OMe group of less steric hinderance at position 1 and a Br atom at position 4 of a naphthyl dioxolane. The OMe group at position 1 was to allow isomerisation to occur at position 2, and the Br atom was to inhibit isomerisation at position 4, thereby inhibiting the formation of the angular naphthopyran.

Most of cyanometalate-based cages is inspired by Prussian Blue FeII bridge FeIII with CN ligand. Those Prussian Blue analogue complexes which have been discussed as catalysts, sensors, molecular magnets, and sieves. Our effort focus on the synthesis of Prussian blue analogue complexes frameworks by using 3,5-dmTPM as spectator ligand in FeII and FeIII metal. The complex [(3,5-MeTPM)2FeII2(��-Cl3)][3,5-MeTPMFeIICl3] (1) was prepared from the reaction of FeCl2 and 3,5-MeTPM in a 1:1 ratio. The salts compound 1 was characterized by 1H NMR spectroscopies, and cyclic voltammetry. Treatment of 1 with excess CN- afforded [(3,5-MeTPM)FeII(CN)3)]- was characterized by NMR, infrared, and cyclic voltammetry. The reaction of 3,5-MeTPM with FeCl3 afforded complex [3,5-MeTPMFeIIICl3] (4) which was proved by element analysis, and cyclic voltammetry. The reaction of 4 with 3equiv. of AgCOOCF3 afforded [(3,5-MeTPM)FeIII(COOCF3)3](6) was characterized by X-ray diffraction and element analysis. Oxygenation of complex [(3,5-MeTPM)FeII(CN)3)]- by I2 afforded [(3,5-MeTPM)FeIII(CN)3)] which was characterized by infrared. The complex 6 was a novel structural mode which for an active site of Fe-Containing SOD (Superoxide Dismutase) enzyme.

Natural product, Morusin was isolated from the root bark of mulberry tree (a variety of Morus alba L.). It had important biological activities including anti- inflammation, potent inhibition of human PLC/PRF/5, T24, KB, OVCAR-3, H441 and HT-29 cells. According to important biological activities and the methods to synthesize Glychalcone and Glyflavone in our laboratory, we worked hard to want to synthesize it. Therefore, we synthesized chromen 6 via six steps from 1,3,5-trihydroxybenzene, including annelation, methylation, Clemmensen reduction, acylation, Fries rearrangement and dehydrogenation. On the other segment, we synthesized acid chloride 11 via five steps from 2,4-dihydroxybenzoic acid, including esterification, protecting PMB and methyl group, hydrolysis and then reacted with oxalyl chloride. With precursors 6 and 11 in hand, the synthesis of prenyldiketone 14 via two steps including addtion-elimination and alkylation. The formation of dimethylmorusin 15 via cyclization, dehydration and cleavage of PMB group in acidic condition. Finally, demethylation with EtSLi we prepared to expect to afford natural product, Morusin. Natural product, Acrovestone was isolated from plant (Acronychia pedunculata) and it had potent cytotoxicity(100% inhibition at 0.5 ug/ml) in the KB tissue culture assay. It also showed significant cytotoxicity against A-549, P-388, and L-1210 cells with ED50 values of 0.98, 3.28, and 2.95 ug/ml, respectively. According to important biological activities and the methods we had studied, we worked hard to want to synthesize it. Now, we had synthesized dibromochromene 23 by bromination of chromen 6, and precursor, bromoacetophenone 20 from 1,3,5-trihydroxybenzene via three steps including methylation, Friedel-Crafts acylation and bromination. Furthermore, we studied prenylation of chromen 6 to synthesize Acronyculatins E 22. Finally, we expected to synthesize natural product, Acrovestone by studying the reaction including palladium-catalyzed coupling, debromination, ring opening, asymmetric reduction and prenylation in the future.

Morusin was isolated from Moraceae plants, and it was a natural product and had biological activity. We had synthesized two precursors of Morusin, 5,2’-dimethoxy-4’-(4-methyl-benzyloxy) morusin 24 and 5,2’- dimethoxy morusin 64. In the research of deprotection, methyl, 4-methyl-benzyl and 4-methoxy–benzyl (PMB), were protecting groups that we wanted to deprotect. The total synthesis of Morusin was our purpose. Theaflavins were synthesized from Catechins during oxidative process. Theaflavins were included in black tea usually, and had much biological activity. The center structure of Theaflavins is a seven-members ring, and that was our initial purpose. We wanted to synthesize (6E,8E)-1,8-dibromo- 3,4,6-trihydroxy-5H-benzo[7]annulen-5-one 52 by 4-bromo-catechol 31 and 5-bromo- pyrogallol 41 ,then made a coupling reaction to get Theaflavins.
