Abstract

Abstract: A novel phosphine-promoted intramolecular cyclization of dicyclopropenones 1 has been described in this contribution. A variety of 2, 3-dihydro-1H-indene-4, 6-diol derivatives 2 and hexahydropentalen-2-one derivatives 3 were obtained selectively in moderate to good yields under mild conditions through different phosphine-promoted reactions. Keywords: cyclization; cyclopropenones; phosphines; selectivity
