3]thiazole with benzimidazole or triazole derivatives were obtained by the regioselective reactions of the 2,2-dicyanooxiranes with 1H1,3-benzimidazol-2-thiol or 5-phenyl-4H-1,2,4-triazol-3-thiol respectively in good to excellent yields. Also, we performed a reaction between 2,2-oxiranedicarbonitrile reagents and potassium thiocyanate in acetic anhydride at room temperature and isolated 2-acetylimino-1,3-oxathiole
通过2,2-二氰基环氧乙烷与1H1,3-苯并咪唑-2-硫醇或5-苯基-4H-1的区域选择性反应,得到了一组稠合[1,3]噻唑与苯并咪唑或三唑衍生物的杂环化合物, 2,4-三唑-3-硫醇分别具有良好到极好的产率。此外,我们在室温下在乙酸酐中进行了 2,2-环氧乙烷二甲腈试剂和硫氰酸钾之间的反应,并分离出 2-乙酰亚氨基-1,3-氧杂硫醇衍生物。
