A CuI-catalyzed synthesis of 1,3-disubstituted allenes from 1-alkynes by the reaction with various N-tosylhydrazones has been developed. This method, which uses readily available starting materials and is operationally simple, offers 1,3-disubstituted allenes in moderate to good yields. The reaction also tolerates various functional groups.
通过与各种N-甲苯磺酰hydr的反应,由CuI催化从1-炔烃中合成1,3-二取代的烯丙基。该方法使用容易获得的起始原料并且操作简单,以中等至良好的产率提供了1,3-二取代的烯。该反应还容许各种官能团。
