Abstract Nine new α-methylene-γ-butyrolactones were synthesized by the Reformatsky condensation of ethyl α-bromomethylacrylate with kelones, aldehydes, and an epoxide. A. unique spirobutyrolactone class was prepared by reaction of the zinc alkyl derivative and N -methylisatins. The compounds were evaluated against L-1210 and P-388 leukemia and the 9KB carcinoma of the nasopharynx. They also were screened
