远程二维核磁共振和NOE差谱法研究新生物碱马尾杉碱N的结构

THE STRUCTURE DETERMINATION OF A NEW ALKALOID PHLEGMARIUINE-N BY LONG-RANGE TWO-DIMENSIONAL AND NOE DIFFERENCE NMR SPECTROSCOPY

    摘要
  • 摘要: 自华南马尾杉Phlegariurus fordii(Baker)Ching中分得新生物碱—马尾杉碱N(Ⅰ)。它含有七个季碳。本工作采用远程13C—1HCOSY和远程增强型1H—1HCOSY新技术与NOE差谱相配合的方法成功地连接被季碳和杂原子分隔开的自旋系统,推定了其结构。

     

    Abstract: A new alkaloid, phlegmariuine-N, was isolated from Phlegmariurus fordii (Baker) Ching. In the present work, a technique of long-range 1H-1H and ~(13)C-1H COSY in combination with NOE difference spectroscopy has been successfully used to connect the spin systems separated by quaterrnary carbons and heteroatom. Its structure has been elucidated as (Ⅰ).
