An air-assisted, functional-group-driven, mild, additive-free, three-component synthetic approach to different 2-oxo acetamidines from 2-oxo aldehydes, secondary amines, and anilines was successfully developed. Mechanistically, the transformation proceeds through a highly unstable system ((RCOCHNN2)-N-1) that rearranges at room temperature and undergoes air-assisted dehydrogenation to different 2-oxo
成功开发了一种空气辅助、官能团驱动、温和、无添加剂、三组分合成方法,用于从 2-氧代醛、仲胺和苯胺中合成不同的 2-氧代乙脒。从机制上讲,转化是通过一个高度不稳定的系统 ((RCOCHNN2)-N-1) 进行的,该系统在室温下重排并在空气辅助下脱氢生成不同的 2-氧代乙脒。
