Application of enantiopure templated azomethine ylids to β-hydroxy-α-amino acid synthesis
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 three (2S,3R) beta-hydroxy-alpha-amino acids (3) in excellent yield, (C) 1998 Elsevier Science Ltd.
