The hydrolysis of a choline carbonate through a metal-free, enzyme-like mechanism has been achieved using a 2-aminobenzimidazole-based deep cavitand as catalyst. The supramolecular catalysis involves three steps: host-guest binding, carbamoylation and enzyme-like hydrolysis. Interestingly the rate-determining step proceeds through a

A one-pot, two-step synthesis of imidazo[1,2-a]benzimidazoles has been achieved by a three-component reaction of 2-aminobenzimidazoles with an aromatic aldehyde and an isocyanide. The reaction involving condensation of 2-aminobenzimidazole with an aldehyde is run under microwave activation to generate an imine

A method using liquid chromatography and a single mix-mode solid-phase extraction cleanup for the simultaneous analysis of thiabendazole [2-(1,3-thiazol-4-yl)-1H-benzoimidazole], carbendazim [(methyl N-(1H-benzoimidazol-2-yl)-carbamate)] and 2-aminobenzimidazole (1H-benzimidazol-2-amine) in concentrated fruit juices is described. The three fungicides were isolated from the samples and

An efficient strategy for the synthesis of a variety of 2-animobenzimidazole derivatives has been developed. The reaction proceeded from o-haloanilines and carbodiimides via copper(I)-catalyzed domino reaction in the presence of tert-butoxide to afford the corresponding 2-animobenzimidazole derivatives in good to

A series of 2-aminobenzimidazole-based MCH1R antagonists was identified by core replacement of the aminoquinoline lead 1. Subsequent modification of the 2- and 5-positions led to improvement in potency and intrinsic clearance. Compound 25 exhibited good plasma and brain exposure, and
