Description A palladium catalyzed intermolecular annulation of cinnamic acids and phenols has been achieved for the selective synthesis of 3-substituted benzofurans. Isotope labeling, competition experiments, kinetic studies, and intermediate trapping have supported a sequence of C-C bond formation and decarboxylation followed by the C-O cyclization pathway.
