2, 2, 6-Tritnethylcyclohesanoiie (111) w, s prepared in 69yo over-all yield from carbethoxycyclohexanoiie. Hal (igeiiatiuii of the ketone I11 gave the haloketones IV and V in excellent yield. The chloroketone IV was converted in 839% yield to the bicyclo epoxyether\ TI which was characterized by hydrolysis and reaction with p-nitrobenzoic acid to give the hydroxyketone IX and the ketoberizoate VIII. The structure of the hydrosyketone IX was ...
