Palladium Catalyzed Skeletal Rearrangement of Spiro tricyclic Olefins: A facile One Pot Strategy for the Synthesis of a Novel Motif with Cyclopentene Fused to Benzofuran and Pyrazolidine

An efficient one pot strategy for the synthesis of a novel framework of benzofuran-pyrazolidine fused cyclopentenes by a palladium catalyzed tandem reaction of cyclopropane-bearing spirotricyclic olefins with 2-iodophenols is reported. In the case of 2-iodoanilines, the protocol afforded functionalized spiro[2.4]-hept-4-enes. ,Chemistry–A European Journal, DOI:10.1002/chem.201301475
