remote stereocontrolled 1,8-conjugate addition of thiazolones to propargylic aza-p-quinone methides formed from propargylic alcohols has been developed with the aid of a chiral phosphoric acid, and this represents the first report on organocatalytic stereocontrolled 1,8-addition of propargylic aza-p-quinone methides. Notably, the remote stereocontrolled activation protocol enables the construction of vicinal
借助于手性磷酸,已开发了将噻唑酮向由炔丙醇形成的炔丙基氮杂对苯醌甲基化物进行远程立体控制的1,8-共轭加成反应,这是关于有机催化立体控制的1,8-加成的首次报道。炔丙基氮杂对苯醌甲基化物。值得注意的是,远程立体控制的活化方案使得能够构建邻位的含硫季碳立体中心和轴向手性四取代的烯丙基,并促进了手性磷酸的化学反应。
