摘要：

alpha-Dibenzylamino aldehydes, derived from the corresponding natural alpha-amino acids, react with metal acetylides to yield anti-amino propargyl alcohols in good yield and diastereomeric excess. syn Amino alcohols are prepared from the. anti diastereo-isomers and all of them are elaborated in few steps to enantiopure amino lactones and hydroxy-piperidin-2-ones.
