摘要：
We have developed an intermolecular conjugate addition of 3a-pyrroloindoline/furoindoline radicals to alpha,beta-unsaturated enones, through visible-light photoredox catalysis. Ir(ppy)(2)(dtbbpy) PF6 was found to be an effective promoter to initiate this reaction from readily available 3a-bromopyrroloindolines/furoindolines. This method was exploited to prepare a series of indole terpenoid-like compounds of potential biological interest.
