A practical and efficient strategy for the chemoselective C–S cross-coupling of 2-mercaptobenzimidazole derivatives with a range of substituted aryliodides is described. Under the optimized conditions of 5 mol% CuI and 100 °C, a variety of S-arylated products were obtained in good to excellent yields (up to 92 %) without the need for assisting ligands.

An expeditious method to access 2-substituted benzimidazoles was developed. Both aromatic (phenols, anilines, and thiophenols) and alkyl nucleophiles (amines and thiols) react with 2-methylsulfonyl benzimidazole under solvent-free conditions to generate a variety of 2-substituted benzimidazoles.

Development of benzimidazole-based compounds as novel capsid assembly modulators for the treatment of HBV infection
HepatitisBvirus (HBV) capsidassemblymodulators (CAMs) represent a promising therapeutic approach for the treatment of HBV infection. In this study, the hit compound (IC = 2.46 ± 0.33 μM) was identified by screening of an in-house compound library. And then novel potent benzimidazole derivatives were designed and synthesized as core assemblymodulators, and their antiviral effects were evaluated
