Synthesis of each of the enanuomers of sitophilate, the male-produced aggregationpheromone of the granaryweevil, is described. Catalytic asymmetric epoxlaattan of -allylic alcohol 2 [with (+)-DIPT] followed, by derivatization with 3,5-dinitrobenzoyl chloride and subsequent recrystallizatton afforded 3a in high enantiomertc and diastereomertc purity. Conversion to epoxy ester 6a and reoloselecative
