8-(l-Phenylthio)cyclopropyl enones can be conveniently prepared via reaction of the lithium salts of a-hydroxymethylene ketones with l-lithio-lphenylthiocyclopropane and are converted efficiently by treatment with aqueous acid to y-keto cyclobutanones and less successfully by thermolysis to y-keto phenylthiocyclopentenes.

Both 1,3-and 1.4-diketones are obtained from common precursors, A-methoxy-Y-phenylthio ketones. These compounds are derived through the novel phenylthio migration reaction of the aldehyde adducts with methoxy(phenylthio)methane upon exposure to enol silyl ethers. The compounds thus obtained are conv
