Reaction of lithiated sulfone 3 with trimethyl(oxiranyl)silane 4 , followed by acid hydrolysis, afforded the (Z)‐allylic alcohol 6 contaminated with its ( E ) isomer. Epoxidation of 6 by the Sharpless procedure yielded the hydroxy epoxide, which was isolated as its enantiomerically pure 3,5‐dinitrobenzoyl derivative 7 and transformed into (+)‐disparlure 1 via alcohol 8 and tosylate 9 .
