从中草药勒党植物中分得一个生物碱,选择性远程DEPT NMR新技术用于识别谱峰,连接被季碳、杂原子分隔的质子自旋系统,确定其结构如(1)所示。
An alkaloid was separated from the herbaceous plants of the Chinese herbal medicine. The selective remote DEPT NMR technique was used to identify the peak of the spectrum and connect the proton-spin system separated by quaternary carbon and heteroatoms. The structure of the proton was confirmed as (1).
