Methyl 9(10), 12(13)-dioxo-octadecanoate (derived from methyl linoleate) and 10, 13-dioxo-11-methyl-octadecanoate (derived from the latex of the rubber plant) were methylated at the methylene carbons located between the two oxo-groups (using Mel, KOH in DMSO) and cyclodehydration furnished a mixture of methyl 9(10),-12(13)-epoxy-10(11), 11(12)-dimethyloctadeca-9(10), 11(12)-dienoates and methyl 10
9(10),12(13)-二氧十八碳烯酸酯(来自亚油酸甲酯)和10,13-二氧-11-甲基十八碳酸酯(来自橡胶厂的胶乳)在位于以下位置之间的亚甲基碳被甲基化两个氧代基团(在DMSO中使用Mel,KOH)和环脱水,得到甲基9(10),-12(13)-环氧-10(11),11(12)-二甲基十八烷基-9(10)的混合物, 11(12)-二烯酸酯和甲基10、13-环氧-11、12-二甲基十八烯10、12-二烯酸酯。
