With the mediation of phosphine, the direct intramolecular coupling of two electrophiles - alkyl halides with electron-deficient olefins - has been successfully realized in an intramolecular conjugate addition manner. The reaction provides a new approach for the synthesis of chromans and relevant analogues.
在膦的介导下,已经成功地以分子内共轭加成的方式实现了两种亲电子体的直接分子内偶联-烷基卤化物与缺电子的烯烃。该反应提供了一种合成苯并二氢吡喃和相关类似物的新方法。
