| Abstract | Base-induced cyclization of active methylene isocyanides with carbamimidothioates for the synthesis of N,1-aryl-4-tosyl/ethylcarboxy-1H-imidazol-5-amines is reported. The diversity of the reactions is exemplified by using various carbamimidothioates obtained from symmetrical N,N-disubstituted, unsymmetrical N,N,N-trisubstituted, and unsymmetrical N,N-disubstituted thioureas. This diversity is further enriched by different isocyanides. A mechanism for the formation of the title compounds is proposed. |
