A series of 47 novel N1-alkylated-2-aryl-5(6)-substituted-1H-benzimidazoles and their three novel indole analogues were synthesized and evaluated for in vitro antifungalactivities against Candida species by the tube dilution method. The results showed that compounds 79 and 80, having pyridine at the position C-2, of benzimidazoles exhibited the greatest activity with MIC values of 6.25–3.12 μg/mL
The iron-catalyzed heterocyclizations from 2-nitroanilines and benzylic alcohols to form benzimidazoles using hydrogen transfer reaction were investigated in this study. In the presence of dppf in toluene at 150 °C, various benzimidazoles were obtained in moderate to good yields within 24 h. The reaction was proposed to proceed via a cascade of alcohol oxidation, nitro reduction, condensation, and
