A rhodium(III)-catalyzed one-pot three-component reaction of N-methoxybenzamide, α-diazoester, and alkyne was developed, providing an alternative way to synthesize isoquinoline derivatives. Mechanistically, it is a relay catalysis, and the reaction occurred via successive O-alkylation and C–H activation processes, both of which were promoted by the same catalyst.
开发了铑(III)催化的N-甲氧基苯甲酰胺,α-重氮酸酯和炔烃的一锅三组分反应,为合成异喹啉衍生物提供了另一种方法。从机理上讲,它是一种中继催化,反应是通过连续的O-烷基化和CH-H活化过程发生的,这两者都是由同一催化剂促进的。
