A copper‐catalyzed cascade reaction of N‐H insertion and oxidative aromatization has been developed. 2‐Arylaminophenols have been prepared in moderate to high yields from the diazo substrates. Moreover, this newly established methodology allows efficient access to natural 1‐oxygenated carbazole alkaloids, such as glycozolicine and murrayafoline A.
已开发出铜催化的N-H插入和氧化芳构化的级联反应。从重氮底物中可以中等到高产率制备2-芳基氨基苯酚。而且,这种新近建立的方法可以有效地获得天然的1氧化咔唑生物碱,例如糖索林碱和MurrayafolineA。
