Tandem conjugate addition by an O-silylcyanohydrin derived carbanion to 5-(1-menthyloxy)-2(5H)-furanone, followed by reaction with an aromatic aldehyde gives two diastereoisomeric adducts. These afford a single product on treatment with tetrabutylammonium fluoride. Reduction with concomitant removal of the menthyloxy group, followed by acid catalysed cyclisation gave a homochiral tetrahydronaphthalene
通过O-甲硅烷基氰醇衍生的碳负离子将串联共轭加成至5-(1-薄荷氧基)-2(5 H)-呋喃酮中,然后与芳族醛反应,得到两个非对映异构体加合物。这些经氟化四丁基铵处理得到单一产物。还原,同时除去薄荷基氧基,然后酸催化环化,得到高手性四氢萘反内酯,它是鬼臼毒素的一种有趣的结构异构体。
