Procedure
A mixture of 2-benzyl-7,7-diphenyl-2,3,3a,4,7,7a-hexahydro-1H-isoindol-4-one (3.4 g) and vinyl chloroformate (0.92 cc) in 1,2-dichloroethane (80 cc) is heated to reflux for 1 hour; the reaction mixture is concentrated to dryness under reduced pressure (2.7 kPa). The residue is crystallized in ethyl ether (20 cc). 7,7-Diphenyl-2-vinyloxycarbonyl-2,3,3a,4,7,7a-hexahydro-1H-isoindol-4-one (2.6 g), m.p. 162° C., is obtained.
