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~(13)C—~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。
The novel alkaloid, Maurilacine N(I), was isolated from the Phungariurus fordii (Baker) Ching. It contains seven quaternary carbons. In this work, long-range (13)C-~1HCOSY and remote enhanced ~1H-~1HCOSY new technologies were combined with NOE differential spectra to successfully connect the spin systems separated by quarter carbon and heteroatoms. Its structure.
