Reaction Steps

The general procedure for the preparation of substrates using 3-ethoxycyclopentenone (0.88 g, 7.0 mmol) and benzylmagnesium chloride (10 mmol, 1 M in diethyl ether) gave, after flash chromatography (2:1 hexanes:ethyl acetate) and Kugelrohr distillation (0.4 torr, 200° C.), the title compound as a white solid (0.58 g, 50%). m.p. 32-33° C. Spectroscopic data were consistent with previously reported data for this compound.3
