Abstract The absolute configurations of heteroxanthin ((3 S ,5 S ,6 S ,3′ R )- 7′,8′-didehydro-5,6-dihydro-β,β-carotene-3,5,3′,6′-tetrol) ex Euglena gracilis and of diadinoxanthin ((3 S ,5 R ,6 S ,3′ R )-5,6-epoxy-7′,8′-didehydro-5,6-dihydro-β,β-carotene-3,3′-diol) from the same source have been established by chemical reactions, hydrogen bonding studies, 1 H NMR and CD. Two previously unknown carotenoids
摘要 异黄质 ((3 S ,5 S ,6 S ,3' R )- 7',8'-didehydro-5,6-dihydro-β,β-carotene-3,5,3',6 的绝对构型'-tetrol) 来自 Euglena gracilis 和 didinoxanthin ((3 S ,5 R ,6 S ,3' R )-5,6-epoxy-7',8'-didehydro-5,6-dihydro-β,β-来自同一来源的胡萝卜素-3,3'-二醇)已通过化学反应、氢键研究、 1 H NMR 和 CD 确定。来自 Trollius europaeus 的两种以前未知的类胡萝卜素(人工制品?),分配了结构 (3 S ,5 S ,6 S ,3' S ,5' R ,6' R )-6,7-didehydro-5,6,5' ,6'-四氢-β,β-胡萝卜素-3,5,6,3',5'-pentol 及其 5 R 差向异构体可作为有用的模型。
