摘要:

以3-氧化木糖为原料,通过Henry反应与硝基甲烷加成,得到两种硝基糖化合物1, 2-O-异丙叉基-3-C-硝甲基-5-对甲苯磺酰基-α-D-呋喃核糖(1)和1, 2-O-异丙叉基-3-C-硝甲基-4-甲烯基-α-D-呋喃核糖(2),其中化合物2为新型的硝基糖化合物.通过应用1D NMR和2D NMR测试了化合物21H NMR、13C NMR、1H-1H COSY、gHSQC和gHMBC,对化合物21H和13C进行了全归属.

关键词: 核磁共振(NMR), 归属, 3-氧化木糖, 硝基糖

Abstract:

A new nitro sugar compound 1, 2-O-isopropylidene-3-C-nitromethyl-4- methenyl-α-D-xylofuranose (2) and a known nitro sugar compound 1,2-O-isopropylidene- 3-C-nitromethyl-5-(p-methylbenzenesulfonyl)-α-D-xylofuranose (1) were synthesized from 3-oxoxylose and nitromethane by Henry reaction. The compound 2 was characterized using NMR spectroscopy techniques, including one-dimensional 1H and 13C NMR, 1H-1H COSY, HSQC and HMBC. The NMR signals were assigned. The molecular structure of compound 2 was determined.

Key words: NMR, assignment, 3-oxoxylose, nitro sugar
