ENHANCEMENT OF OPTICAL PURITY OF A PRODUCT BY REMOVING UNWANTED DIASTEREOMERS IN THE COURSE OF A CHIRAL SYNTHESIS: NEW SYNTHESIS OF THE STEREOISOMERS OF 2,8-DIMETHYL-1,7-DIOXASPIROUNDECANE, THE PHEROMONE OF ANDRENA WILKELLA

(2R,6S,8R)-, (2S,6R,8S)- and (2R,6R,8S)-2,8-dimethyl-1,7-dioxaspiroundecanes were synthesized, and their specific rotations and optical purities were discussed.
