摘要:报道了一种简便易行的绿色合成4-羟基苯基-1′-O-D-吡喃葡萄糖苷(即熊果苷及其端基异构体)新方法,采用固体酸蒙脱石K-10或4A分子筛为催化剂,将四苄基保护的葡萄糖(2)或α-三氯乙酰亚胺酯糖给体(3)与氢醌直接进行糖基化反应,最高以86%的产率获得4-羟基苯基-2,′3,′4,′6′-四-O-苄基-1′-O-D-吡喃葡萄糖苷(4),进而脱除苄基保护,定量获得熊果苷及其端基异构体(1)。中间体(4)的结构经IR、MS、1H NMR及元素分析等测试技术进行了确认,化合物(1)的理化数据与文献值相同。
A new greeen chemosynthesis of 4-hydroxyphenyl-1'-O-D-glucopyrano-side, arbutin and its anomer α-arbutin, is reported. With solid acid, montmorillonite K-10 or 4A molecular sieves as catalysts, benzylprotected donor(2) or α-trichloroacetimidate (3) was glycosylated with hydroquinone to obtain intermediate (4) in a yield of 86%, and then compound (1) was quantitatively obtained after the deprotection. This method is very benign to environment. The structure of compound (4) was confirmed by IR, MS, ^1H NMR and elemental analysis, and the data of target compound ( 1 ) are the same as those from references.
