Highly functionalised spirocyclic pyrans can be obtained through the Achmatowicz rearrangement of furyl carbinols by taking advantage of the different rates of reaction for epoxidation and nucleophilic addition. Through this methodology, spirocyclic units of various ring sizes can be selectively generated with complete stereocontrol.
利用环氧化反应和亲核加成反应的不同速率,可以通过糠基甲醇的 Achmatowicz 重排获得高官能度的螺环吡喃。通过这种方法,可以选择性地生成各种环尺寸的螺环单元,并具有完全的立体控制能力。
