Synthesis of some novel 2-(6-fluorochroman-2-yl)-1-alkyl/acyl/aroyl-1H-benzimidazoles by the condensation of o-phenylenediamine with 6-fluoro-3,4-dihydro-2H-chroman-2-carboxylic acid, and subsequent reactions with different types of electrophiles, have been reported. Some compounds exhibited promising anti-bacterial activity against Salmonella typhimurium; however, they showed poor activity against S. aureus. The biological activity against PDE IV for potential anti-asthamatic effect, and against DP-IV and PTP 1B for potential anti-diabetic effects was disappointing.
