Reaction of the complex of silver chromate and iodine with a γ-hydroxyolefinic acid (isoricinoleic) yielded 13-iodo-9,12-epoxyoctadecanoic acid, which on treatment with m-chloroperbenzoic acid gave a quantitative yield of 9,12-dioxo-octadecanoic acid.

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.

Ricinoleic acid (1) has been converted into methyl 9,13-bisacetoxy-12-oxooctadecanoate (17), an envisaged key intermediate for the synthesis of prostanoids.As a preliminary, 17 has been transformed into the title compound (14) which has been earlier conve
