Diazoacetates derived from α- or β-allenic alcohols, prepared using the glyoxylic acid chloride p-toluenesulfonylhydrazone method, undergo regioselective intramolecular cyclopropanation in the presence of a copper (II) catalyst in refluxing toluene, leading to synthetically useful di- or trisubstituted methylenecyclopropyl lactones. The diastereoselectivity of the process has been studied.
