Abstract

The first total syntheses for the (Z)-15-methyl-10-hexadecenoic acid and the (Z)-13-methyl-8- tetradecenoic acid were accomplished in seven steps and in 31–32% overall yields. The (trimethylsilyl) acetylene was the key reagent in both syntheses. It is proposed that the best synthetic strategy towards monounsaturated iso methyl-branched fatty acids with double bonds close to the ω end of the acyl chain is first acetylide coupling of (trimethylsilyl) ...
