Synthesis of the optically active forms of 4,10-dihydroxy-1,7-dioxaspiro[5.5]undecane and their conversion to the enantiomers of 1,7-dioxaspiro[5.5]undecane, the olive fly pheromone
Both the enantiomers of l,7-dioxaspiro[5.5]undecane, the major component of the pheromone of the olivefly (Dacusoleae), were synthesized from (S)-malic acid.
