Abstract
A new method has been developed for the synthesis of 1,3-benzothiazol-2(3 H )-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(3 H )-ones with methoxycarbonylamine group at the C-6 atom. Modifications of the obtained compounds were performed. Authors: A. V. Velikorodov, A. K. Kuanchalieva, and V. A.
