摘要: 以对甲氧基苯甲醛为起始原料,经过肟化脱水、交叉偶联、亲核加成和氧化闭环4步反应合成了目标产物3(4甲氧基苯基)4甲基5异噻唑胺,并且总收率可达4715%。通过工艺条件优化,得到了盐酸羟胺和硫代乙酰胺的最佳用量。目标化合物的结构通过GCMS和1H NMR进行了鉴定。实验结果表明:该反应条件温和,产品收率高,后处理简单,三废较少,具有良好的工业应用前景。

Abstract: Utilize pmethoxybenzaldehyde as a starting material, after oximationdehydration, crosscoupling, nucleophilic addition and oxidation closedloop fourstep reactions synthesized target product 3(4methoxyphenyl)4methyl5isothiazoleamine,and the total yield is up to 4715%.By optimizing the process conditions obtained the optimum dosage of hydroxylamine hydrochloride and thioacetamide.The structure of the target product was confirmed by GCMS and 1H NMR. The experimental results show that the reaction condition is mild, product yield is high, simple workup, less three wastes, and with good prospects for industrial applications.
