solved in 40 ml of methylene chloride and treated with 2.1 ml of T H F containing 63 mg of 70 % HClO, solution at room temperature for 1.5 hr. The reaction mixture was washed with saturated sodium chloride solution. The methylene chloride layers were dried over Na2S0, and evaporated to dryness. The products were isolated by silica gel column chromatography, to give 63 nig of g3 (RI = CHI, Rz = H) (mp
