title: Synthesis of benzofuro[3,2-b]pyridines via palladium-catalyzed dual C-H activation of 3-phenoxypyridine 1-oxides.
abstract: An efficient oxidative cyclization to straightforward synthesis of benzofuro[3,2-b]pyridine 1-oxides with high regioselectivity via Pd-catalyzed intramolecular dual C-H activation was developed. The resulting products could be deoxygenated easily to the corresponding benzofuro[3,2-b]pyridines in excellent yields.
