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
当相应的多烯(12)和(13)用二甲基二环氧乙烷处理时,邻位的双-和三-环氧化物(14)和(20),以及它们的非对映异构体伴侣可方便地生产。以类似的方式,用二甲基二环氧乙烷处理(25)得到(14)的立体异构体(26)。邻位双环氧化物(14),(20)和(26)的酸催化仿生环化反应生成相应的二羟基四氢呋喃产物,包括用于合成(±)-柠檬酸病毒(1)的立体异构体(27)。)。
