Stereoselective introduction of an unsubstituted propargyl group to various glycals was achieved using a Ferrier type reaction with allenyltributyltin(IV). The stereoselectivity was observed based on the conformational preference of glycals as well as steric control of rigid bicyclic systems.
使用与烯丙基三丁基锡(IV)的Ferrier型反应,可将未取代的炔丙基立体选择性地引入各种糖基。基于糖基的构象偏好以及刚性双环系统的空间控制,观察到立体选择性。
