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

The synthesis of functionalized benzothiadiazine 1,1-dioxidederivatives was achieved through a novel three-component intramolecular CH 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 multicomponentsynthesis 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.

A series of trichloroacetamidine derivatives, obtained by addition of amines to trichloroacetonitrile, was evaluated for positive inotropic activity on isolated cat heart papillary muscles. Increased contractility, not antagonized by beta-adrenergic blockade with sotalol or reserpine pretreatment, was observed in this assay with a variety of N-substituted trichloroacetamidine derivatives. More extensive pharmacological studies with the 3-indolylmethyl analogue 2 showed that this amidine in dogs, 5 mg/kg iv, produced a positive inotropic effect more pronounced than that of ouabain, 50 microgram/kg iv. Several of the trichloroacetamidines were found to be inhibitors of guinea pig kidney and calf heart Na-K-dependent ATPase and to have specificity for these enzymes different from that of ouabain. Bacterial mutagenic activity was observed with three members, 2,3, and 12, of the series.
