Abstract The transformation of a 10-membered ring sesquiterpene, germacrone, into guaiane-type sesquiterpenes by suspension cultured cells ofCurcuma zedoaria was investigated. Germacrone was converted into several sesquiterpenes, some of which were isolated from theCurcuma spp. plants through, the key intermediate, (4R,5R)-germacrone 4,5-epoxide, and their structures were determined by spectral and
摘要 研究了莪术悬浮培养细胞将十元环倍半萜基麦角酮转化为愈创木酚型倍半萜。Germacrone 被转化为几种倍半萜,其中一些是从 Curcuma spp 中分离出来的。植物通过关键中间体 (4R,5R)-germacrone 4,5-epoxide,通过光谱和化学证据确定了它们的结构。一些衍生物的构型与从姜黄属植物中分离的倍半萜的构型相反。芳香族,C. 龙加和C。芹菜。还分离了一种eudesmane 型产品并确定了其结构。从结构上推测,germacrone 通过中间体 (1S, 10S)-germacrone 1,10-epoxide 转化,并通过germacrone 1 的转化进一步证实,10-环氧化物经酸处理成同品。还确定了两种新产品的结构,并推导了它们通过姜黄酮和二氢姜黄酮的转化机制。
