Novel aryl-β-C-glucosidation method using glucal boronate was developed. This protocol can offer several advantages including use of non-toxic, easily handling glucal boronate as a crystalline solid and storable at room temperature for several months. Tri-O-methylnorbergenin (8,10-di-O-methylbergenin), an anti-HIV active bergenin derivative, was concisely synthesized by application of the aryl-β-C-glucosidation
开发了使用葡糖基硼酸酯的新型芳基-β-C-葡糖苷化方法。该协议可以提供几个优点,包括使用无毒,易于处理的硼酸硼酸甘油酯为结晶固体,并且在室温下可以储存几个月。通过应用芳基-β-C-葡糖苷化方法,简明地合成了抗HIV活性的卑尔根衍生物三邻甲基降冰片原(8,10-二邻邻甲基卑尔根)。
