A total of 51 novel benzimidazoles were synthesized by a 4-step reaction starting from basic compound 4-fluoro-3-nitrobenzoic acid under relatively mild reaction conditions. The structure of the novel benzimidazoles was confirmed by mass spectra as well as (1)H NMR spectroscopic

A novel strategy for an unconventional Pictet-Spengler reaction has been developed for the regioselective cyclization of the imidazole ring system at the C2 position. The developed strategy was utilized to develop a diversity-oriented parallel synthesis for bis(heterocyclic) skeletal novel analogs

An efficient method for the solid-phase synthesis of trisubstituted [1,3,5]triazino[1,2-a]benzimidazole-2,4(3H,10H)-diones from resin-bound amino acids is described. N-acylation of the primary amine of a resin-bound amino acid with 4-fluoro-3-nitrobenzoic acid, followed by displacement of the fluoro group and reduction of the
Two series of novel acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitors containing benzimidazole core structure were synthesized by a four-step reaction pathway starting from 4-fluoro-3-nitrobenzoic acid as the basic compound. The structure of the novel benzimidazoles was characterized and confirmed by
4-Fluoro-3-nitrobenzoic acid attached to a solid support was shown to react under mild conditions with a wide range of functionalized phenols to yield, after cleavage, the corresponding biaryl ethers in excellent purity. In a similar fashion, biaryl thioethers could be
