Reaction of fatty acids with dimethyldioxirane in acetone produces ketoacids in 9-12percent yields in which the ketone carbonyl is distributed along the fatty chain.The n-1 position appears to be preferred.Lactones of hydroxy fatty acids are oxidized by this reagent, but in low yields, to the corresponding ketoacids.Biphasic epoxidations with methylethyldioxirane in 2-butanone were conducted with methyl oleate and methyl ricinoleate to give the corresponding epoxides in high yield, and olive oil and tallow were cleanly epoxidized by this procedure as well.KEY WORDS: Chain functionalization, dioxirane, epoxidation, oleic acid, ricinoleic acid, tallow.

Three 7-hydroxyalkanoic acids not previously reported in microorganisms were found in extracts from saponified whole cells of Mucor spp. grown under oxygen limiting conditions.On the basis of evidence from mass spectrometry, infrared spectroscopy, gas chromatographic procedures and chemical conversions, they were confirmed to be 7-hydroxydecanoic, 7-hydroxydodecanoic and 7-hydroxytetradecanoic acids.The racemates of the former two acids were synthesized and compared with the isolates.These acids were found in the hydrolyzates of extractable and residual parts of lyophilized cells with a chloroform-methanol (2:1) mixture.The hydroxy acid contents of eight species of the genus Mucor grown in stationary liquid medium were also determined.
