Bimetallic titanium complex catalyzed enantioselective oxidation of thioethers using aqueous H2O2 as a terminal oxidant

A series of dimeric amino alcohol derived Schiff bases with various chiral amino alcohols and their corresponding bimetallic titanium complex were generated in situ. Thereafter with the in situ generated complexes, the asymmetric oxidation of prochiral aryl alkyl sulfides has been investigated using aqueous H2O2 as a terminal oxidant. During the study we found that the use of methanol or tert-butanol as an additive improved the catalytic activity in terms of both conversion and enantioselectivity. Moreover we observed a co-operative effect of the two reactive units of the bimetallic complex, which results in high reactivity as well as enantioselectivity compared to the corresponding monomeric complex. With this improved catalytic system several aryl alkyl sulfides and 1,3-dithianes were oxidised to the corresponding sulfoxides with good to high enantioselectivity (ee 78-99%) and conversion (70-99%). Unlike the monomer, oxidation of substrates like benzyl phenyl sulfide was achieved with high enantioselectivity as well as high yield.

Discovery of potent HIV-1 protease inhibitors incorporating sulfoximine functionality

Based on the unique property of sulfoximine and the homodimeric C2 structural symmetry of HIV-1 protease, a novel class of sulfoximine-based pseudosymmetric HIV-1 protease inhibitors was designed and synthesized. The sulfoximine moiety was demonstrated to be important for HIV-1 protease inhibitor potency. The most active stereoisomer (2S,2?S) displays a potency of 2.5 nM (IC50) against HIV-1 protease and an anti-HIV-1 activity of 408 nM (IC50). A possible mode of action is proposed.

EFFECT OF THE STRUCTURE OF CATALYST AND NUCLEOPHILE ON THE EFFICIENCY OF NUCLEOPHILIC CATALYSIS IN SNVin-SUBSTITUTION REACTIONS

The effect of the structure of tertiary amines on the rate of forming vinylammonium salts has been studied.These salts are intermediates in the nucleophilic catalysis of SNVin-substitution.The example used is the aminolysis of p-nitrophenyl trans-beta-chlorovinyl sulfone in acetonitrile at 25 deg C.It was discovered that these reactions possess a higher sensitivity towards the effect of the electronic and spatial factors of the amine structure than does the vinylation of nucleophiles, primary and secondary amines, by the salts indicated.It was shown by analyzing the results that the process may be proceeding in different situations (accumulation or rapid consumption of the intermediate) depending on the nature of the catalyst and nucleophile.Various types of catalysis are therefore being effected, such as general-base, nucleophilic, and nucleophilic with general base assistance.
