    通过N1-乙酰化作用将4-(取代的苄基)-1,2-二氢-3H-吡唑-3-一衍生物与2,3,4,6-四-O-酰基-α-D-吡喃葡萄糖基溴化物进行O-糖基化吡唑环。
    摘要:
    描述了4-(取代的苄基)-3-(2,3,4,6-四-O-酰基-β-D-吡喃葡萄糖基氧基)-1H-吡唑衍生物2的实用制备。通过在吡唑的N1位引入吸电子取代基,例如乙酰基,可以促进4-(取代的苄基)-1,2-二氢-3H-吡唑-3-酮衍生物3的O-糖基化。戒指。1-乙酰基-4-(取代的苄基)-1,2-二氢-3H-吡唑-3-酮10与2,3,4,6-四-O-酰基-α-D-吡喃葡萄糖基溴化物5反应在乙腈中存在碳酸钾以提供1-乙酰基-4-(取代的苄基)-3-(2,3,4,6-四-O-酰基-β-D-吡喃葡萄糖基氧基)-1H-吡唑衍生物11高产。当将2,3,4,6-四-O-新戊酰基-α-D-吡喃葡萄糖基溴化物(5b)用作糖基供体时,在甲醇中存在碳酸氢钾的情况下,将所得的O-糖基化产物11 N1-脱乙酰基,而糖基部分的去保护作用不佳,从而以优异的产率提供了2。使用该策略合成了莫格列净依替膦酸酯的合成中间体2b(1b)。
