for synthesis of novel dispirooxindolecyclo[pyrrolo[1,2-c]thiazole-6,5'-thiazolidine] derivatives without any catalysts under ultrasonic condition has been developed. Combining with the advantages of sonochemistry, such as mild reaction conditions, good yield and short reaction times, we have made a progress on construction of novel disiproheterocyclic compounds via the 1,3-dipolar cycloaddition of
已经开发了一种在超声波条件下无需任何催化剂即可合成新型二螺氧杂环吲哚环[吡咯并[1,2-c]噻唑-6,5'-噻唑烷]衍生物的简便高效的一锅三组分方法。结合声化学的优点,如反应条件温和,收率高,反应时间短,我们已经通过偶氮甲亚胺的1,3-偶极环加成反应制备新型二异杂环化合物。特别进行了一些实验来研究超声对环加成反应的加速机理。
