Abstract

A palladium-catalyzed cascade radical cyclization and C-H amination of 1,7-enynes with perfluoroalkyl iodides and hydroxylamine has been developed for the rapid construction of tricyclic quinolin-2(1H)-one scaffolds. The reaction proceeded smoothly to give a series of tricyclic quinolin-2(1H)-one derivatives in high yields. Notably, the late-stage modifications of various drugs were realized by using this method.
