In this paper, we report an efficient synthetic method for thioester formation from sodium thiosulfate pentahydrate, organic halides, and aryl anhydrides. In the one-pot two-step reactions developed in this study, sodium thiosulfate was used as the sulfur surrogate for acylation with anhydrides, followed by substitution with organic halides through the in situ generation of thioaroylate. Furthermore
在本文中,我们报告了一种由五水合硫代硫酸钠,有机卤化物和芳基酸酐形成硫酯的有效合成方法。在这项研究开发的一锅两步反应中,硫代硫酸钠被用作硫代用品,用酸酐进行酰化,然后通过原位生成硫代芳基酸酯被有机卤化物取代。此外,使用我们开发的方法可以成功合成两种重要的有机化合物。一锅两步反应的优点是操作简便,结构多样的产品收率达42%至90%,使用相对低毒且无味的试剂,并且易于大规模操作。
