Concise synthesis of N-thiomethyl benzoimidazoles through base-promoted sequential multicomponent assembly.

ABSTRACT: An efficient method for the synthesis of N-thiomethyl benzimidazoles from o-phenylenediamines, thiophenols, and aldehydes via C-N/C-S bond formation under metal-free conditions is described. A broad range of functional groups attached to the substrates were well tolerated in this reaction system. Stable and low-toxicity paraformaldehyde was used as the carbon source.
