CHIRAL LIGANDS CONTAINING HETEROATOMS. V ENANTIOSELECTIVE KETONE REDUCTION USING CHIRAL DIAMINES/METAL HYDRIDE SYSTEMS
New chiral reducing agents prepared from zinc or magnesium dichloride, optically active diamines and diisobutylaluminium hydride, have been studied.These complexes were used in the reduction of a series of prochiral ketones and, compared with similar tin(
