A catalyst-free method for the highly regioselective hydrated ring-opening and formylation of quinazolinones was developed. This reaction realized the direct arylation of two nitrogen atoms on quinazolinones and realized the regioselective ring-opening of quinazolinone and subsequent acylation of methyleneamine through the nucleophilic addition of a water molecule to an imine carbon atom. It showed reasonable functional group compatibility and provided one-pot access to a variety of -arylformyl derivatives in moderate to excellent yields.
开发了一种无催化剂的喹唑啉酮高区域选择性水合开环甲酰化方法。该反应实现了喹唑啉酮两个氮原子的直接芳基化,并通过水分子对亚胺碳原子的亲核加成,实现了喹唑啉酮的区域选择性开环和随后的亚甲胺酰化。它表现出合理的官能团相容性,并提供了一种一锅法以中等至优异的收率获得各种 -芳基甲酰基衍生物的方法。
