本文报道以1-溴-2,3,4,6-四-O-乙酰基-a-D-吡喃糖与苯二酚在氢氧化钠的丙酮-水溶液中反应, 生成熊果苷类似物. 由^1HNMR测定了糖苷的端基异构体.

关键词: 溴化合物, 吡喃糖, 葡萄糖, 类似物, 糖苷, 乙酰基, 苯二酚, 熊果苷

Arbutin analogs were synthesized by reacting 1-bromo-2,3,4,6-tetra-O-acetyl-a-D-glucopyranose or galactopyranose with dihydroxybenzenes followed by mild hydrolysis with methanolic ammonia. The anomeric configurations of these glycosides were assigned based on 1H NMR and comparison of 1-C chem. shifts on the sugar moieties.

Key words: BROMINE COMPOUNDS, PYRANOSE, GLUCOSE, ANALOGUE, GLYCOSIDE, ACETYL GROUP, BENZENEDIOL, ARBUTIN
