Abstract

The rearrangement of donor–acceptor cyclopropanes has been demonstrated for the first time using Brønsted acid catalysis. A series of substituted cyclopentene derivatives were obtained in moderate to good yields and moderate diastereoselectivities. Further control experiments and synthetic applications have also been carried out.
