  一种噻唑-4-甲酸的制备方法

  摘要：

  本发明公开了一种噻唑‑4‑甲酸的制备方法,可以解决重要传统农药杀菌剂品种之一噻菌灵的老工艺所使用的原料价格相对高昂、收率低的问题,包括以下步骤：首先以L‑半胱氨酸盐酸盐与甲醛、吡啶生成噻唑烷‑4‑甲酸，然后噻唑烷‑4‑甲酸与甲醇、HCl气体反应生成噻唑烷‑4‑甲酸甲酯，噻唑烷‑4‑甲酸甲酯再与乙腈、MnO2反应生成噻唑‑4‑甲酸甲酯，最后噻唑‑4‑甲酸甲酯在氢氧化钠作用下水解得到产品噻唑‑4‑甲酸。该工艺合成路线简单、反应条件温和、成本低、环保安全，具有很好的应用前景，同时也具有较好的社会效益和较高的经济效益。

  Both base‐assisted non‐concerted metallation–deprotonation (nCMD) and concerted metallation–deprotonation (CMD) have been identified as two potent operating mechanisms in palladium‐catalysed direct CH coupling of oxazole and thiazole‐4‐carboxylate esters with halides through base‐ and solvent‐effect experiments. Novel C2‐ and C5‐selective CMD direct arylation procedures in oxazole‐ and thiazole‐4‐carboxylate

  两个基地辅助非一致金属化-去质子化（NCMD）和协同金属化-去质子化（CMD）已被确定为在钯催化的直接C上两个有效的操作机构通过与卤化物恶唑的耦合和噻唑-4-羧酸酯ħ碱和溶剂效应实验。然后通过控制电子和空间因素之间的平衡，设计了恶唑和噻唑-4-羧酸酯系列中新颖的C2和C5选择性CMD直接芳基化方法。值得注意的是，钯催化剂和底物之间的电荷相互作用被确定为控制选择性和减少CMD反应中空间因素的影响的参数。
