✦ Synopsis
A simple and general asymmetric synthesis of b-amidophosphonates is described. The method involves the highly selective addition (up to 95% d.e.) of diethyl phosphite to various chiral a,b-unsaturated carboxylic amides derived from chiral aminoalcohols.

threo-a-Dibensylamino-B-hydroxyesters (2) have been synthesised with high diastereoselectivity through the NaBH reduction of a-dibenzylamino-B-oxoesters (4) and then tranformed into threo-a-amino-B-hydroxyac?ds. a-Amino-B-hydroxyacids are derivatives of primary importance both as enzymatic inhibito
