制备方法与用途

应用

5-硝基吲哚-3-甲醛可用作医药合成中间体。该化合物可通过将5-硝基-1H-吲哚作为反应原料来制备，并用于制备新型的3,5-二取代1H-吲哚衍生物，对胰腺癌细胞株BxPC-3具有较好的抑制活性。

制备

在0℃下，逐步滴加POCl₃(9.2ml，98.5mmol)至DMF(9.5ml，123.1mmol)中，搅拌0.5小时后，加入5-硝基-1H-吲哚(2.0g，12.3mmol)，然后在室温下反应1.5小时。随后将反应液倒入大量冰水中，并用6N NaOH调节pH至7，再用乙酸乙酯萃取三次，浓缩后得到2.34g灰色固体5-硝基吲哚-3-甲醛，产率为98%，纯度为95.2%。

  质子交换蒙脱石介导的乙酸异苄酯反应：在扎鲁司特的合成中的应用

  摘要：

  具有出色表面特性的质子交换蒙脱石（H-mont）可以在中孔中提供丰富的酸性位点，并且可以作为一种高效的非均相催化剂，用于通过（杂）芳烃的Friedel-Crafts烷基化合成含杂环的二芳基甲烷杂乙酸乙酸酯在温和的反应条件下不需要任何添加剂或惰性气氛。使用该策略，以高收率完成了含吲哚的二芳基甲烷13的克级合成，从而制备了Zafirlukast。此外，H-mont可用于乙酸杂苄酯5p与多种醇和1,3-二羰基化合物的亲核取代反应。

  摘要：

  芳基和杂芳基（二甲基氨基）甲基的C–N键的氧化裂解可通过在环境条件下，弱碱存在下使用分子碘作为弱氧化剂来实现。游离NH和含有各种取代基的取代的吲哚的C 3甲酰化的重要反应是由相应的曼尼希碱完成的。该方法还可以扩展为芳基和其他杂芳基醛和酮的合成。此外，该方法的实用性已成功以克为单位进行了证明。
