摘要

Chiral stabilised azomethine ylids derived from the reaction of (5S)-5-phenylmorpholin-2- one (1) with aldehydes undergo efficient and highly diastereocontrolled cycloaddition with a second molecule of aldehyde to furnish products (2) which may be converted into enantiomerically pure threo (2S, 3R) β-hydroxy-α-amino acids (3) in excellent yield.
