Palladium-catalyzed carbon-hydrogen activation at methoxy groups for cross-coupling reactions: a new approach to substituted benzo[b]furans
摘要:
Palladium catalyzed C-H activation of methoxy groups as the key step in a cross-coupling reaction of o-iodomethoxybenzenes with bromo olefins is described. By this method, substituted benzofurans are synthesized in moderate to good yields.
