摘要：

Reported here is the asymmetric synthesis of N-Boc-protected (2S,3S)-3-amino-2-hydroxyoctadecanoic acid, a component of ralstonin A and ralstoamide A. Key synthetic steps include alkylation of chiral Ni(II) complex of glycine Schiff base, conversion of COOH to keto acid (CO-COOH) and reduction of the carbonyl group to generate alpha-hydroxy functionality. The structure and absolute configuration of (2S,3S)-N-Boc-3-amino-2-hydroxyoctadecanoic acid was shown to be identical to that of the naturally occurring compound.
