title: Aluminum chloride-mediated acylation of methylenecyclobutanes. A facile synthetic protocol for the construction of substituted cyclopentenes.
abstract: Reactions of methylenecyclobutanes (MCBs) with acyl chlorides produce the corresponding substituted cyclopentene derivatives in moderate to high yields via ring enlargement in the presence of aluminum chloride under mild conditions. A plausible mechanism has been proposed on the basis of control and deuterium labeling experiments.
