The vicinal bis- and tris- epoxides (14) and (20), together with their diastereoisomeric partners are conveniently produced when the corresponding polyenes (12) and (13) are treated with dimethyldioxirane. In a similar manner, treatment of (25) with dimethyldioxirane leads to the stereoisomer (26) of (14). Acid-catalysed, biomimetic, cyclisations of the vicinal bis-epoxides (14), (20) and (26) then

Using key functional dissections, the synthesis of spirohezenolides is examined through a three-component strategy that features a 1,2-addition to couple tetronate and aldehyde components forming the C2-C3 bond and a Stille coupling to install the third sulfone-containing component The macrocycle is completed by an intramolecular Julia-Kocienski reaction to form the C10-C11 trans-disubstituted olefin. Application of this strategy is described in progress toward the synthesis of (+/-)-spirohexenolide B.
