β-Lactones were prepared by irradiation of 3-diazodihydrofuran-2,4- diones via Wolff rearrangement proceeding with retention of the configuration of the migrating carbon atom. In the presence of alcohols or thiols, but not amines, the corresponding 3-(alkoxycarbonyl)- or 3-[(alkylsulfanyl)carbonyl]- β-lactones were obtained. 5-Alkyl-3-diazodihydrofuran-2,4-diones gave exclusively trans-3,4-disubstituted β-lactones.
