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
