Procedure

Solid sodium acetate (2.0 g) was added to a stirred solution of this ester (5.4 g) in dimethylformamide (80 ml) at 0°-5° C. 30% Hydrogen peroxide solution (10 ml) was added dropwise over 15 minutes and the mixture was stirred for a further 1 hour at 0°-5° C. then slowly diluted with water (240 ml). The solid product was dried and recrystallised from ether-petroleum ether 40°-60° C. to give the epoxide, ethyl 6-benzoyl-5-oxo-2,7-dioxabicyclo-[4.1.0]hept-3-ene-3-carboxylate (mp 96°-98° C.).
