Microwave Assisted Synthesis of New Benzimidazoles

Abstract

New potentially bioactive and highly functionalized benzimidazoles were synthesized by using microwave irradiation methodology in multi-steps: construction of benzimidazole ring, N-methylation and electron transfer Calkylation (followed by base-promoted nitrous acid elimination) or S-alkylation.2][3][4][5][6] Heterogeneous reactions facilitated by supported reagents on various
