Substrate-induced synthesis of 6H-Chromeno[4,3-b]quinolin-6-ones has been developed directly from anilines, 4-hydroxycoumarins and DMSO under air without any catalysts and additives in one pot. This protocol highlights dual roles of 4-hydroxycoumarins which were not only used as reactants but also activated DMSO to provide one-carbon unit in the desired products.
6 H - Chromeno[4,3 - b ]quinolin-6-ones 的底物诱导合成直接由苯胺、4-羟基香豆素和 DMSO 在空气中开发,无需任何催化剂和添加剂。该协议强调了 4-羟基香豆素的双重作用,它们不仅用作反应物,而且还激活 DMSO 以在所需产品中提供单碳单元。
