  A convergent synthesis of four stereoisomers of the sex pheromone of the western corn rootworm (8-methyldecan-2-yl propionate, 1) from commercially available chiral starting materials is reported. The key step was Julia–Kocienski olefination between chiral BT-sulfone and chiral aldehyde. This synthetic route provided the four stereoisomers of 1 in 24–29% total yield via a six-step sequence.

  Enantiomerically pure alcohols produced by Thermoanaerobium brockii alcohol dehydrogenase (TBADH)-catalyzed asymmetric reduction of polyfunctional ketones are useful building blocks for natural products synthesis. This advantage has been demonstrated by a total synthesis of all four isomers of 8-methyldec-2-yl propanoate, the sex pheromone emitted by the female western corn rootworm, Diabrotica virgifera virgifera LeConte. These four isomers were obtained in a very short procedure (either three or five steps) with an enantiomeric purity that exceeds 99% using a single chiral building block, (2S,8S)-(+)-2,8-dihydroxynonane. The latter diol, characterized by a synthetically useful C2 symmetry, was obtained by TBADH-catalyzed reduction of nonane-2,8-dione.
