摘要: 8,2'-O-环化-9β-D-腺呤阿拉伯糖苷是阿糖腺苷合成过程中的一个关键性中间体,该化合物的NMR数据只有1H-NMR谱的糖环1'位质子化学位移和偶合常数的报道,13C-NMR谱未曾报道。本文用2D-NMR、NOE-DIF等技术,对它的1H、13C-NMR谱进行归属,进一步明确了它的结构。

Abstract: 8, 2'-o-cyclo-Ara-A is the key intermediate for the synthesis of Ara-A. There is a few reports on the NMR of this compound, only H-1' chemical shifts and coupling constants were reported, but no 13C-NMR data reported. 1H and 13C NMR spectra of 8, 2'-o-cyclo-Ara-A were assigned by 1H-1H COSY, 13C-1H COSY and NOE-DIFFERENCE techniques. The conformation of sugar ring was further confirmed.

Key words: 8,2'-o-cydo-Ala-A, 2D-NMR, NOE-DIFFERENCE
