摘要: 本文研究了群柱内酯萜(Ⅰ)的二维1H同核COSY、C-H COSY、远距C-H COSY谱,根据这些信息和经验规律归属了(Ⅰ)的1H及13C谱峰,二维远距C-H COSY提供了相隔两、三个键的C-H偶合信息,因此,在很多方面可以代替灵敏度很低的INADEQUATE技术,得到C-C联结的信息。

Abstract: This paper reports the study of DEPT, 2D H-H COSY, C-H COSY and long-range C-H COSY spectra of Clavulactone,a Dolabellane type diterpene.The long-range C-H COSY plays a very important role in the elucidation of H-C-C, H-C-C-C connectivities,therefore it is to some extent an alternative to the insensitive inadequate.

Key words: Clavulactone, 2D NMR, C-C connectivity
