A base promoted protocol for the synthesis of benzo[a]imidazo[5,1,2-cd]indolizines from 2-arylimidazo[1,2-a]pyridines and benzyne precursors under metal-free conditions has been developed. Without a transition metal, double C(sp2)–H activation of 2-phenylimidazo[1,2-a]pyridines under basic conditions was achieved. This method is also applicable for the annulation of imidazo[1,2-a]pyrimidine and naphthylamine
已开发了在无金属条件下由2-芳基咪唑[1,2- a ]吡啶和苯炔前体合成苯并[ a ]咪唑并[5,1,2- cd ]吲哚嗪的基础促进方案。没有过渡金属,双C(SP 2)- H 2苯基咪唑的活化[1,2一]在碱性条件下的吡啶达到了。该方法也适用于在相同条件下咪唑并[1,2- a ]嘧啶和萘胺的环化反应。这些环状分子表现出荧光特性,因此评价了它们的光物理性质。
