Rh(III)-Catalyzed C–H Bond Activation along with “Rollover” for the Synthesis of 4-Azafluorenes
摘要:
An intramolecular reaction of 3-alkynyl and 3-alkenyl-2-arylpyridines selectively gave 4-azafluorene compounds in the presence of a catalytic amount of [Cp*RhCl2](2) and Cu(OAc)(2). Pyridine-directed C-H bond activation along with "rollover" are likely to be key steps of this transformation.
