Abstract

The oxidative dearomatization of 3-(3-alkynyl-4-hydroxyphenyl)propanoic acid is combined with a cascade transition-metal catalyzed cyclization/addition/aromatization/lactamization sequence, which provides a novel approach to prepare furoquinolinone and angelicin derivatives in a convergent and efficient manner.© 2012 American Chemical Society
