摘要

通过对其n -乙酰基衍生物的旋光度、uv、ir、pmr和质谱数据的分析，确定了从麻瓜属植物中分离得到的去甲啡类新生物碱norlaureline(1)和puterine(4)的结构。通过将1和4分别转化为月桂碱(3)和普卡汀甲基醚(6)，证实了所提出的结构。

Structure elucidation of norlaureline and puterine, new noraporphine alkaloids from Guatteria elata.

The structures of norlaureline (1) and puterine (4), new noraporphine alkaloids isolated from Guatteria elata (Annonaceae), were established by interpretation of the optical rotation, uv, ir, pmr, and mass spectral data of their N-acetyl derivatives. Proposed structures were confirmed by transformation of 1 and 4 to laureline (3) and pukateine methyl ether (6), respectively.
