The title compound 1 was synthesized via addition of dichlorocarbene to dimethyl trars-3-hexenedioate (5), using o-nitrophenylselenic acid-elimination to form the double bonds. Reaction of dichlorocyclopropane 8 with ozone on silica gel furnished the monoketone 10; no diketone 11 could be isolated upon further exposure of 10 to O3/SiO2. When the bis(p-toluenesulfonate) 13b was treated with t-BuOK,
