制备方法与用途

5-氯-2-糠醛的应用与制备

5-氯-2-糠醛可用作医药合成中间体，并可通过糠醛为原料制备。此外，它还应用于化工领域，例如在混凝土多功能复合外加剂的制备中。

制备过程

将30mmol糠醛和30mmol ZnCl₂溶解在30mL AcOH中，在室温下搅拌1小时后，加入5mL乙酸中的底物（10mmol）。随后将混合物加热至70°C并继续搅拌24小时。之后，使用100mL乙醚稀释此混合液，并依次用0.1N Na₂S₂O₃（50mL）、0.1N NaHCO₃（20mL）和盐水（20mL）洗涤。将有机相干燥处理（使用Na₂SO₄），然后除去溶剂得到粗产物，最后通过柱色谱法或真空蒸馏纯化，最终可获得5-氯-2-糠醛，收率为10%。

• Room-Temperature Suzuki-Miyaura Coupling of Heteroaryl Chlorides and Tosylates
  作者：Junfeng Yang、Sijia Liu、Jian-Feng Zheng、Jianrong Steve Zhou

  日期：2012.11

  Suzuki–Miyaura coupling of heteroaryls is an important method for the preparation of compound libraries for medicinal chemistry and materials research. Although many catalysts have been developed, none of them have been generally applicable to the coupling reactions of heteroaryl chlorides and tosylates at room temperature. We discovered that a catalyst combination of Pd(OAc)2 and XPhos (2-dicyclohexylphosphanyl-2′

  杂芳基的 Suzuki-Miyaura 偶联是制备用于药物化学和材料研究的化合物库的重要方法。尽管已经开发了许多催化剂，但它们都没有普遍适用于杂芳基氯与甲苯磺酸酯在室温下的偶联反应。我们发现 Pd(OAc)2 和 XPhos（2-二环己基膦酰基-2',4',6'-三异丙基联苯）的催化剂组合可以有效地催化这些偶联。除了催化剂的选择，在含水醇溶剂中使用氢氧化物碱对于快速偶联也是必不可少的。这些条件促进了活性催化剂（XPhos）Pd0 的快速释放，并加速了催化循环中的金属转移。大多数杂芳基氯（31 个实例）和甲苯磺酸盐（17 个实例）的主要家族在室温下在几分钟到几小时内达到完全转化。该方法可以很容易地扩大规模以进行克级合成。此外，我们检查了整个反应中偶联伙伴的相对反应性。富电子杂芳基氯化物和甲苯磺酸盐的反应速度比缺电子杂芳基化合物慢，顺序为吲哚、吡咯呋喃、噻吩>吡啶。类似地，缺电子芳基硼酸的反应

• Preparation of Potassium Alkoxymethyltrifluoroborates and Their Cross-Coupling with Aryl Chlorides
  作者：Gary A. Molander、Belgin Canturk

  DOI：10.1021/ol800532p

  日期：2008.6.5

  A wide variety of alkoxymethyltrifluoroborate substrates were prepared via SN2 displacement of potassium bromomethyltrifluoroborate with various alkoxides in excellent yields. These alkoxymethyltrifluoroborates were effectively cross-coupled with several aryl chlorides. This method provides a unique dissonant disconnect that allows greater flexibility in the design of new and improved synthetic pathways
