Condensation of sulfone (XXI) with aldehyde (XXXVII), followed by treatment with benzoyl chloride affords adduct (XXXVIII). Reductive elimination of sulfone (XXXVIIII) with sodium amalgam leads to the conjugated diene (XXXIX). Both O-silyl groups of (XXXIX) are removed by treatment with tetrabutylammonium fluoride, providing diol (XL). Then, esterification of (XL) with acetic anhydride and DMAP furnishes diacetate (XLI).
