Novel microwave induced method for the synthesis of thiazolidine-2,4-dione motif under solvent phase conditions is developed. Further we report an efficient, microwave assisted method for the parallel syntheses of biologically important 5-benzylidene-thiazolidine-2,4-dione and 5-benzylidene-2-thioxothiazolidine-4-one compounds under solid-phase and solvent-free conditions. A comparative study between
开发了一种新型的微波诱导方法,用于在溶剂相条件下合成噻唑烷-2,4-二酮基序。此外,我们报告了一种高效,微波辅助的方法,可在固相和无溶剂条件下平行合成生物学上重要的5-亚苄基-噻唑烷-2,4-二酮和5-亚苄基-2-噻吩并噻唑烷-4-酮化合物。描述了已开发的微波方法与常规方法之间的比较研究。我们还说明了背后的可能机制,以解决哌啶,乙酸和硅胶增强Knoevenagel缩合反应的原因。
