Procedure
Combine (E)-4-(p-methoxybenzyloxy)-2-benzoyloxymethyl-1-chlorobut-1-ene (1.02.6 g, 7.18 mmol) with methylene chloride (16 mL) and water (1 mL) and stir rapidly. Add 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (1.79 gm, 7.90 mmol). After 2 hours, filter the reaction mixture, rinse the filter cake with methylene chloride (200 mL) and concentrate the filtrate in vacuo. Chromatograph on silica gel eluting with 1/2 ethyl acetate/hexane to give the title compound as an oil. Rf =0.25; silica gel, 1/2 ethyl acetate/hexane.
