The structure of an unknown yellow base from Menisperum dauricum DC. (Menispermaceae) was determined to be 5, 6, 9-trimethoxy-7H-dibenzo [de, h] quinolin-7-one (1) by spectral data and total synthesis. It was named menisporphine and the skeletal name"oxoisoaporphine"was proposed for this new type of alkaloid. The biosynthesis route of oxoisoaporphine-type alkaloids in plants is suggested.
通过光谱数据和全合成,确定了来自 Menisperum dauricum DC.(Menispermaceae) 中的一种未知黄色碱的结构,通过光谱数据和全合成确定为 5, 6, 9-三甲氧基-7H-二苯并 [de, h] 喹啉-7-酮(1)。它被命名为 menisporphine,并为这种新型生物碱提出了 "oxoisoaporphine "这一骨架名称。提出了氧化异阿扑啡类生物碱在植物中的生物合成途径。
