Complete diastereostereoselection was attained for the addition of acetylide and benzyloxymethyl anions to a chiral aldehyde and an imine derived from meso-tartaric acid, leading to a facile synthesis of (2S,3S,4R,5R,6Z)-2-amino-1,3,4,5-tetrahydroxyoctadecene as its pentaacetyl derivative in enantiomerically pure form.
对乙炔和苄氧基甲基阴离子与来自酒石酸的手性醛和亚胺的加成实现了完全的非对映体选择性,从而方便地合成了其五乙酰衍生物—(2S,3S,4R,5R,6Z)-2-氨基-1,3,4,5-四羟基十八烯,以对映体纯净的形式。
