Rh(I)-Catalyzed Intramolecular [3 + 2] Cycloaddition Reactions of 1-Ene-, 1-Yne- and 1-Allene-Vinylcyclopropanes.

Abstract

New Rh(I)-catalyzed intramolecular [3 + 2] cycloaddition reactions of 1-ene-, 1-yne and 1-allene-vinylcyclopropanes have been developed, affording an efficient and versatile synthesis of cyclopentane- and cyclopentene-embedded bicyclic structures.
