Highly functionalized 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.
通过利用环氧化反应和亲核加成反应的不同速率,呋喃甲醇的Achmatowicz重排反应可制得高度官能化的螺环吡喃。通过这种方法,可以在完全立体控制的情况下选择性地生成各种环大小的螺环单元。
