苦皮素A的化学结构讨论

摘要

One insecticidal active compound, angulatin A. Was isolated from an insecticidal plant. Celastrus Angu-latus Maxim. In this paper,using a combination of 1 D OH, 13C NMR.NOE and DEPT) and 2 D NMRC'H-'H COSY, HSQCHMBC and NOESY) techniques, its 'H and 13C NMR spectras was completely assigned and analyzed. Its structure in the literature was corrected by HMBC technique.%对苦皮素A进行了1H和13C MNR检测,通过DEPT和1H-1H COSY、HSQC、HMBC等2 D NMR技术对该化合物所有的1H和13C NMR信号进行了全归属和详细解析,并采用HMBC技术对文献中与苦皮素A化学结构相关的错误报道进行了修正.
