A novel silver-mediated highly selective synthesis of polysubstituted pyrroles by the CâH/CâH oxidative cross-coupling/cyclization of terminal alkynes with β-enamino esters has been developed. This protocol represents a simple, efficient and selective way to construct polysubstituted pyrroles in good yields from basic chemical materials.
通过 CâH/CâH 氧化交叉耦合/环化末端炔和δ-烯氨基酯,开发了一种新型银介导的高选择性多取代吡咯合成方法。该方法是一种简单、高效、选择性强的方法,可从基本化学材料中以良好的产率合成多取代吡咯。
