A facile and efficient one-pot synthesis of halogenated pyridin-2(1H)-ones from a series of readily available enaminones under Vilsmeier conditions is described, and a mechanism involving sequential halogenation, formylation, and intramolecular nucleophilic cyclization is proposed.
本文描述了一种在 Vilsmeier 条件下，由一系列易得的烯胺酮一锅法高效合成卤代吡啶-2(1H)-酮的方法，并提出了一个涉及顺序卤化、甲酰化和分子内亲核环化的反应机制。
