Stereoselective synthesis of (1S,3R,5R,7S)-(+)-sordidin, the natural male-produced aggregation pheromone of the banana weevil Cosmopolites sordidus (Germar) starting from 5-benzyloxy-(2E)-pentene-1-ol is described. The key transformations employed in the synthesis are Sharpless asymmetric epoxidation, Ueno–Stork cyclization, and Jacobsen kinetic resolution.
立体选择合成(1 S,3 R,5 R,7 S)-(+)-冬青素,从5-苄氧基-(2 E)-开始,香蕉象鼻Cosmopolites sordidus(Germar)的雄性天然产生的聚集信息素。描述了戊烯-1-醇。合成中采用的关键转变是Sharpless不对称环氧化,Ueno-Stork环化和Jacobsen动力学拆分。
