Vinylcyclopropanation of olefins via 3-methoxy-1-propenylrhodium(I).
New cyclization reactions forming vinylcyclopropanes were developed wherein an alkenylrhodium(I) possessing a methoxy group at the allylic position as a potential leaving group acts as an allylic carbene equivalent. By this protocol, a vinylcyclopropane was installed in a complex cyclic structure in a single operation via successive multiple carbon-carbon bond formations.
