ABSTRACT A simple and efficient protocol for the synthesis of 2-aminobenzothiazoles by a ligand-free copper-catalyzed tandemreaction has been developed. In the presence of CuBr and t-BuOK, a variety of 2-haloanilines (halogen = Br, I) underwent the reaction with thiocarbamoyl chloride efficiently to afford the corresponding 2-aminobenzothiazoles in good yields (83–94%). The features of this method
A series of 2-aminobenzothiazoles were synthesized by using 2-halogen-substituted anilines (halogen = Cl, Br, I) and dithiocarbamates in the presence of KOt-Bu. This simple and efficient protocol lets the reactions undergo in a smooth and rapid way to afford the corresponding 2-aminobenzothiazoles in good yields. It is noteworthy that the present process allows the construction of 2-aminobenzothiazoles
A simple and efficient protocol for the synthesis of 2-aminobenzothiazole derivatives is described. 2-Chloroanilines were treated with thiocarbamoyl chloride in the presence of Pd(dba)2 and t-BuOK to afford the corresponding 2-aminobenzothiazoles in good to excellent yield via a tandem manner.
