A chiral hydrazone derived from d-glyceraldehyde: a convenient starting material for the stereoselective synthesis of α-hydrazino acids
摘要:
The chiral hydrazone synthesized from 2,3-di-O-benzyl-D-glyceraldehyde and benzoic acid hydrazide undergoes addition with methylmagnesium bromide in the presence of cerium trichloride in a diastereoselective manner. The major addition compound can be easily transformed into alpha-hydrazinopropanoic acid in four steps in 57% overall yield. (C) 1997 Elsevier Science Ltd.
