摘要: 用DEPT和二维NMR技术包括:1H-1H COSY,1H-13C COSY,NOESY,特别是1H-13C COLOC对两个多酯基取代的倍半萜生物碱的化学及立体结构进行了研究,并对其1H和13C NMR谱峰进行了归属。

Abstract: DEPT and 2D NMR techniques including 1H-1H COSY, 1H-13C COSY, NOESY and 1H-13C COLOC were used to investigate the structures of two sesquiterpene alkaloids with polyester groups. It worth noted specially that 1H-13C COLOC is a very powerful tool for the location of each substituent on the skeleton. The stereo structures were deduced from the coupling constants in1H NMR and NOESY.
