Cu-catalyzed method for the synthesis of 3,3′-bipyrroles from homopropargylic amines through tandem aerobic oxidative cyclization involving the formation of C–C bond has been developed. The features of this reaction are a small number of Cu catalysis and simple starting substrates. Moreover, this procedure exhibits good functional group tolerance and a series of 3,3′-bipyrroles derivatives are obtained
已经开发了一种铜催化的方法,该方法通过涉及形成C–C键的串联好氧氧化环化反应,由均丙基胺合成3,3'-联吡咯。该反应的特征是少量的Cu催化和简单的起始底物。此外,该方法表现出良好的官能团耐受性,并且以中等至良好的产率获得了一系列的3,3'-联吡咯衍生物。
