Methyl 9(10),12(13)-dioxo-octadecanoate (derived from methyl linoleate) and 10,13-dioxo-11-methyloctadecanoate (derived from the latex of the rubber plant) were methylated at the methylene carbons located between the two oxo-groups (using MeI, 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 10,13-epoxy-11,12-dimethyloctadeca-10,12-dienoate respectively.

Unsaturated fatty esters can be easily transformed into ketoesters through a two-step process. The highly efficient epoxidation is carried out with tert-butyl hydroperoxide (TBHP) in α,α,α-trifluorotoluene (TFT) using a Ti-silica heterogeneous catalyst. The formed epoxide is easily rearranged by a heterogeneous Br?nsted acid, with Nafion-silica SAC13 as the most efficient one. Both reactions can be combined in a tandem process, with separation of the Ti-silica catalyst by filtration from the reaction medium and addition of the second acid catalyst to perform the second reaction. Each catalyst is separated individually and can be reused, with or without re-activation, under the same conditions to maximize the productivity.
