New titanium complexes, TiLCl2(THF) and TiL2, containing the tridentate chiral Schiff-base ligand, L, prepared from the condensation reaction of 2,4-pentadione and (1R,2S)-(?)-1-aminoindanol, were synthesized and characterized by various analytical methods including X-ray crystallography. Ligand L acted as a dianionic tridentate ligand and, owing to a chiral center in the aminoindanol part, imparted chirality to its titanium complexes. The newly synthesized titanium complexes and previously reported analogous Ti complexes were used as catalysts in the cycloaddition of CO2 to propylene oxide as the first representatives of titanium complexes with tridentate Schiff base ligands to have been used for this purpose. These complexes provided high selectivity toward cyclic propylene carbonate (>99%) and showed considerable activities with TOF values up to 131 h?1 in comparison with the previously reported catalyst systems.

New chiral derivatizing agents have been prepared through a simple, short-step synthesis. The absolute configuration of alpha-chiral carboxylic acids can be assigned on the basis of the NMR chemical shift difference between diastereomeric esters. Because of the modular structures of the agents, the anisotropic effect could be easily manipulated to afford large chemical shift differences even in polar solvents.

A new method for the stereoselective synthesis of 3-aminoindan-1-ones from triflates of salicylic sulfinyl imines and ethylene glycol vinyl ether has been developed. The reaction sequence starts with a regioselective Heck reaction followed by stereoselective Lewis acid mediated annulation. Acidic cleavage of the sulfinamides produced pure (R)- and (S)-3-aminoindan-1-ones, which were successfully isolated and incorporated into active HIV-1 protease inhibitors.

Chiral beta-amino alcohols are very important chiral building block for preparing bioactive compounds for use in pharmaceutical and fine chemical industries. Synthesis of chiral beta-amino alcohols by transaminase is big challenging due to the strict substrate specificities and very low activity of the enzyme. In this work, a (R)-selective omega-transaminase (MVTA) from Mycobacterium vanbaalenii was employed as a biocatalyst for the first time for the synthesis of chiral beta-amino alcohol via kinetic resolution and asymmetric reductive amination. The enzyme was purified and characterized. Kinetic resolution of a set of racemic beta-amino alcohols including two cyclic beta-amino alcohols by MVTA was demonstrated, affording (R)-beta-amino alcohols, (1S, 2S)-trans-2-aminocyclopentanol and (1R, 2S)-cis-1-amino-2-indanols in >99% ee and 50?62% conversion. Asymmetric reductive amination of three alpha-hydroxy ketones (10?300 mM) by MVTA was conducted, (S)-beta-amino alcohols were obtained with >99% ee and 80?99% conversion. Preparation experiment for the reductive amination of 200 mM 2-hydroxyacetophenone by the resting cells of recombinant E. coli (MVTA) was proceeded smoothly and product (S)-2-amino-2-phenylethanol was obtained with 71% isolated yield, >99% ee and 68.6 g/L/d volumetric productivity. The current research proved that the MVTA is a robust enzyme for the preparation of chiral beta-amino alcohol with high volumetric productivity.
