been developed for the synthesis of 1,3-benzothiazol-2(3H)-ones with carbamate function based on the adducts of the 1,4-addition of thioacetic acid to 2-R-N,N'-dimethoxycarbonyl-1,4-benzoquinone diimines. Refluxing the 2-thioacetyl-substituted dicarbamates in ethanol in the presence of hydrochloric acid gave 1,3-benzothiazol-2(3H)-ones with methoxycarbonylamine group at the C-6 atom. Modifications of
基于硫代乙酸的1,4-加成物与2-R- N,N'-的加合物,已开发出一种新的合成具有氨基甲酸酯功能的1,3-苯并噻唑-2(3 H)-的方法。二甲氧基羰基-1,4-苯醌二亚胺。在盐酸的存在下,将2-硫代乙酰基取代的二氨基甲酸酯在乙醇中回流,得到在C-6原子上具有甲氧基羰基胺基的1,3-苯并噻唑-2(3H)-。对获得的化合物进行修饰。
