We describe a simple and efficient one-pot method for condensing bisulfite adducts of aromatic aldehydes directly with 2,4-thiazolidinedione catalyzed by acetic anhydride. The two main highlights of this study are the one-pot condensation of bisulfite adducts with 2,4-thiazolidinedione in non-aqueous media and the use of Design of Experiment to understand and optimize the reaction conditions.

我们描述了一种简单有效的一锅法,用于直接与乙酸酐催化的2,4-噻唑烷二酮缩合芳族醛的亚硫酸氢盐加合物。这项研究的两个主要亮点是亚硫酸氢盐加合物与2,4-噻唑烷二酮在非水介质中的一锅缩合,以及使用实验设计来了解和优化反应条件。然后使用其他活性亚甲基化合物(如丙二腈)推广该方法。
