of the sphingofungin family, sphingofungin F exhibits interesting physiological activities with a structural unit of an alpha-substituted alanine. Described herein is an efficient and convenient stereoselective synthesis of sphingofungin F from L-(+)-tartaric acid, which utilizes Sharpless asymmetric epoxidation of allylic alcohol and Lewis acid-catalyzed intramolecular epoxide-opening reaction with
作为鞘氨醇单胞菌家族的新成员,鞘氨醇单胞菌F具有有趣的生理活性,其结构单元为α-取代的丙氨酸。本文描述了从L-(+)-酒石酸高效有效地立体选择性地合成鞘氨醇单糖F的方法,该方法利用了烯丙醇的Sharpless不对称环氧化和路易斯酸与N-亲核试剂催化的分子内环氧化物开放反应,从而引入了另一个两个理想的立体中心。使用维蒂希反应将侧链官能团结合到手性链段中。
