Abstract: The title ligand(A) was synthesized through condensation of 2-pyridine aldehydeand L-methyl cysteine hydrochloride.The isomers of (A) were separated by column chromatography.The in-situ prepared catalyst from (A) with [Rh(COD)CI]2(COD:cyclooctadiene) has been used to catalyze the asymmetric hydrosilylation of acetophenone.The resultsshowed that only the configuration of C4, but not that of C2 affected the optical yield andconfiguration of the products.

Key words: pyridyl-carbomethoxy-thiazolidine, ligand, asymmetric hydrosilylation
