A novel class of substituted benzo[d]imidazo[5,1-b]thiazol-1-amine derivatives was synthesized utilizing a one-pot Cu-catalyzed cycloaddition of benzothiazole, trichloroacetonitrile, various amines and terminal alkynes in acetonitrile at room temperature. The speed of this simple four-component reaction along with mild conditions, high yields, readily available starting materials, the ease of work-up without using pollutant precious metals–catalysts, and column chromatography are important features of the presented procedure.

The synthesis of functionalized benzothiadiazine 1,1-dioxide derivatives was achieved through a novel three-component intramolecular C–H activation reaction of trichloroacetonitrile, benzenesulfonyl chloride, and various primary amines. This reaction was performed in the presence of catalytic copper(I) and L-proline as the ligand in tetrahydrofuran at room temperature.

A water-accelerated multicomponent synthesis of organic target molecules has been used as a key method for the preparation of novel imidazole derivatives. The three-component condensation reactions of primary amines with trichloroacetonitrile in the presence of ninhydrine in water are developed as efficient and clean green synthetic procedures for the high-yielding preparation of imidazoles.
