The new chiron (S)-6-phenylthio-2-hexanol (3) was prepared in high enantiomeric excess by baker's yeast reduction of the corresponding ketone. Enantioenriched alcohols 1, 2 and 3, prepared previously by a similar procedure, or their racemic counterparts, were transformed into ring closed compounds 5-methyl-2-(phenylthio)tetrahydrofuran (9), 6-methyl-2- (phenylthio)tetrahydropyran (10), 2-methyl-1-phenylsulfonyl cyclopropane (14), cyclobutane (15), cyclopentane (16), and a bee pheromone, (2S,6R,8S)- 2,8-dimethyl-1,7-dioxaspiro[5.5]undecane (20).
