Stimulation of aflatoxin biosynthesis by lipophilic epoxides
Abstract:
Epoxy fatty acids added to the culture media either with the inoculum or at the end of exponential growth phase stimulated aflatoxin production by toxigenic strains of Aspergillus flavus and Aspergillus parasiticus. This effect did not appear when the unsaturated fatty acids used for the synthesis of the epoxides and the polyhydroxyacids (which can be considered to be derived from the opening of the oxirane ring) replaced the epoxides in the culture media. No significant differences were detected in the lipid fractions (diglycerides, sterols, triglycerides, free fatty acids, sterol esters) extracted from the mycelia grown in the presence of any of the fatty acid derivates.

Oxidation of Alkenes: Anti Dihydroxylation with Peroxy Acids
Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
