Two structurally unidentified alkaloids (tentatively named bases III and IV), isolated from Menispermum dauricum DC. (Menispermaceae), were found to be dauriporphine (1), a known oxoisoaporphine-type alkaloid, and 2, 3-dihydromenisporphine (3), a new alkaloid of the same type, respectively. The structure of dauriporphine was confirmed by synthesis of 4, 5, 6, 9-tetramethoxy-7H-dibenzo [de, h] quinolin-7-one (1).
从Menispermum dauricum DC.(Menispermaceae)中分离出两种结构不明的生物碱(暂时命名为碱基III和碱基IV)。(Menispermaceae)中分离出的两种结构不明的生物碱(暂定为碱 III 和碱 IV),分别是已知的氧代异阿朴啡类生物碱--多瑞泊芬(1)和同类新生物碱--2, 3-二氢苯异泊芬(3)。通过合成 4, 5, 6, 9-四甲氧基-7H-二苯并[de, h]喹啉-7-酮(1),证实了达里泊啡的结构。
