Abstract The preparation of ent -kaur-6, 16-diene and ent - 18-hydroxykaur-6, 16-diene from epicandicandiol and of ent -3β, 18-dihydroxykaur-6, 16-diene from foliol is described. On incubation with Gibberella fujikuroi ent -kaur-6, 16-diene gave 7-hydroxykaurenolide and 18-hydroxykaur-6, 16-diene afforded 7, 18-dihydroxykaurenolide, whilst ent -6α,7α-epoxy-3β,18-dihydroxykaur-16-ene was obtained from ent -3β
摘要 描述了从表姜二醇制备ent -kaur-6, 16-diene 和ent - 18-hydroxykaur-6, 16-diene 以及从foliol 制备ent -3β, 18-dihydroxykaur-6, 16-diene。在与藤黑赤霉属 - kaur-6、16-二烯孵育后得到 7-羟基贝壳杉内酯,18-羟基kaur-6、16-二烯得到 7, 18-二羟基贝壳杉内酯,而 ent -6α,7α-epoxy-3β,18-dihydroxykaurenolide 16-烯由ent -3β,18-dihydroxykaur-6,16-diene 得到。注意到 6, 7-环氧化在贝壳杉内酯形成中可能的生物合成意义。
