摘要：

Epoxidation of methyl (9Z, 11E)-octadecadienoate (1) with various epoxidizing agents viz. m-chloroperoxybenzoic acid, dimethyl dioxirane, methyltrioxorhenium/hydrogen peroxide, potassium peroxomonosulfate (Oxone, 2KHSO(5). KHSO4. K2SO4)/tetrahydrothiopyran-4-one, and Novozyme 435/hydrogen peroxide is described. The reactions furnished the corresponding mono-epoxy [methyl (11,12E)-epoxy-(92)-octadecenoate (2) and methyl (9,102)-epoxy-(11E)-octadecenoate (3)] and a mixture of diastereomers of syn- and anti-diepoxy-stearate [methyl (9,10Z;11,12E)-diepoxystearate (4a-4d)], which were identified by a combination of spectroscopic and spectrometric analyses.
