Asymmetric dihydroxylation with AD-mix-alpha [or AD-mix-beta] carried out on an appropriate ketodiene precursor afforded (2S, 6S, 8S) [or (2R, 6R, 8R)] 2,8-dihydroxymethyl-1,7-dioxaspiro[5,5]undecane. Subsequent synthesis of (+)-2,8-dimethyl-1,7-dioxaspiro[5.5]undecane (insect pheromone) and (+)-2-iodomethyl-8-acetyloxymethyl-1,,7-dioxaspiro[5,5]undecane are described.
