Abstract

stereochemistry stereochemistry (general, optical resolution) O 0030 44 -041 α-Amino Acidate-Ru(II) Catalysts for Asymmetric Transfer Hydrogenation: First Utilization of α-Amino Acids as an Efficient Ligand. -Ru-complexes (I) derived from potassium salts of α-amino acids and Ru 2 Cl 4 (arene) 2 prove to be efficient catalysts for the asymmetric transfer hydrogenation of ketones from alcohols. Enantiomeric excesses of the products reach 92%. -(OHTA, T.; NAKAHARA, S.; SHIGEMURA, Y.; HATTORI, K.; FURUKAWA, I.; Chem. Lett. (1998) 6, 491-492; Dep. Mol. Sci. Technol., Fac.
