Baker yeast hydrogenation of carbonyl activated double-bonds-enantioselective synthesis of the (S)-form of the dihydroterpenediol secreted by danaus-chrysippus and of a pheromone of callosobruchus-chinensis L

The (S)-forms of (E)-3,7-dimethyl-2-octene-1,8-diol (secreted by male danaid butterflies) and of (E)-3,7-dimethyl-2-octene-1,8-dioic acid (a pheromone of the azuki bean weevil) were synthesized via stereoselective hydrogenation by baker’s yeast of the carbonyl activated double bond of achiral precursors.
