2,2'-Azobis(2-methylpropionitrile) (98 mg) and tributyltin hydride (0.95 ml) were added to a solution of methyl 2-[(3R,4R)-3-isocyano-2-oxo-4-allylazetidin-1-yl]-3-methylbut-2-enoate (740 mg) in benzene (15 ml), and the mixture was refluxed for 20 minutes. The reaction mixture was chromatographed on silica gel (15 g) eluting with a mixture of hexane and ethyl acetate (5:1-3:1) to give methyl 2-[(4R)-2-oxo-4-allylazetidin-1-yl]-3-methylbut-2-enoate (660 mg).
