Efficient and convenient syntheses of (2S,3S)-safingol and its natural (2S,3R)-isomer have been developed from 3,4,6-tri-O-benzyl glycals. The key step is the one-pot reduction of an azide, saturation of the double bonds and debenzylation under catalytic hydrogenation.
已经从3,4,6-三-O-苄基糖基化合物中开发了高效便捷的(2 S,3 S)-safingol及其天然(2 S,3 R)-异构体的合成方法。关键步骤是一锅还原叠氮化物,双键饱和和催化氢化下的脱苄基作用。
