An efficient stereospecific synthesis of optically active 4-allylazetidinones (6, 7, 11, and 15a,b) has been accomplished using silver-promoted coupling reaction of allylsilanes 5 and 14b with 4-chloroazetidinones (3, 4, and 10a,b) derived from penicillins.
使用银促进的烯丙基硅烷5和14b与4-氯氮杂环丁烷酮(3、4和10a,b)的偶联反应已完成了光学活性4-烯丙基la啶酮(6、7、11和15a,b)的有效立体定向合成。来源于青霉素。
