We apply a chiral anionic phase‐transfer system for the catalytic asymmetric bromoaminocyclization and bromocycloetherification of momo‐functional benzo‐cyclic alkenes. Various brominated tricyclic benzo‐heterocycles were produced with up to 99% yields and 99% enantiomeric excess. The resulting enantioenriched hexahydro‐benzoindoles are key building blocks of bioactive molecules.
我们将手性阴离子相转移系统用于momo-功能苯并环烯烃的催化不对称溴氨基环化和溴环醚化。各种溴化三环苯并杂环化合物的产率高达99%,对映异构体过量99%。所得的对映体富集的六氢苯并吲哚是生物活性分子的关键组成部分。
