    描述:
    2-氧代-2-(4-氧代四氢-2H-吡喃-3-基)乙酸乙酯一水合肼溶剂黄146 作用下, 以915 g的产率得到1,4,6,7-四氢吡喃o[4,3-c]吡唑-3-羧酸乙酯
    参考文献:
    名称:
    一种1,4,6,7-四氢吡喃[4,3-C]吡唑-3-羧酸 的合成方法
    摘要:
    本发明公开了一种1,4,6,7‑四氢吡喃[4,3‑C]吡唑‑3‑羧酸的合成方法。该方法为:以草酸二乙酯和四氢吡喃酮为原料,得到2‑氧代‑2‑(4‑氧代四氢‑2H‑吡喃‑3‑基)乙酸乙酯(2);再与水合肼关环生成1,4,6,7‑四氢吡喃o[4,3‑c]吡唑‑3‑羧酸乙酯(3);最后水解反应得到目标产物1,4,6,7‑四氢吡喃[4,3‑C]吡唑‑3‑羧酸(4)。本发明解决了现有技术中原料贵和收率低的问题。该路线反应条件温和,纯化简单,以较高的收率和高纯度制得终产物,适合工艺放大。
