A happy medium: The title reaction of cyclopropenyl carbinols and carbinylamines gives carbo- and heterocycles with a [6.1.0] bicyclic ring fused to an aromatic ring (see scheme, Alloc=allyloxycarbonyl, Boc=tert- butyloxycarbonyl). These reactions are the first examples of the formation of medium-sized rings by the intramolecular cyclopropanation of an alkene with a donor-substituted rhodium carbenoid, which is not generated from a diazo compound.
