A three combinatorial step solid-phase traceless synthesis of benzimidazoles is reported. The aldehyde resin was reductively alkylated by amines, the resin bound secondary amines were reacted with o-fluoronitrobenzenes, and the resulting o-nitroanilines were reduced by tin chloride. The primary aniline was acylated by acid chlorides. Exposure to acetic acid at elevated temperature cleaved and cyclized

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
