Reductive workup after ozonization gave mainly the-hydroxy aldehyde 2 and again onlyminor amounts of the ketone 3. In carbon tetra-chloride ozonolysis of 1 produced some formic acid trimethylsilyl ester (6), an equivalent amount of ketone 3, and an unstable substance that was not isolated in pure form. Tenta-
