A novel microwave-assisted approach for the one-pot Cu(I)-catalyzed A3-coupling/decarboxylative coupling (PA2-coupling) of a propiolic acid, an aldehyde, and an amine, resulting in the formation of diversely substituted 1,4-diamino-2-butynes,is described. It is noteworthy that this new multicomponent coupling provides an efficient access to introduce alkyl and aryl group at the 1,4-position of the
一种新颖的微波辅助方法,用于一锅铜(一)催化丙酸,醛和胺的A 3偶联/脱羧偶联(PA 2偶联),从而形成不同取代的1描述了4-4-二氨基-2-丁炔。值得注意的是,这种新的多组分偶联提供了在1,4-二氨基-2-丁炔的1,4-位上引入烷基和芳基的有效途径。
