Research Abstract

The objective of this research is stereoselective synthesis of chiral-at-metal complexes and the development of their asymmetric catalysis. High enantioselectivity has been achieved in the following three asymmetric reactions: titanium-catalyzed asymmetric epoxidation of enol esters, aluminum-catalyzed asymmetric oxidation of thioacetals, and vanadium-catalyzed asymmetric synthesis of non-protected cyanohydrins
