1-Allyl(2-bromopropyl)-3-carboxy(carbalkoxy)methyl-2-aminobenzimidazolium halides and their 2-iminobenzimidazoline forms were synthesized. Their cyclization into functionalized imidazo[1,2-a]benzimidazole derivatives was studied. Some further transformations of obtained imidazobenzimidazoles with the participation of reactive substituents and an activated methylene group were studied.

This study demonstrates the successful synthesis and cyclization of functionalized imidazo[1,2-a]benzimidazole derivatives using 1-Allyl(2-bromopropyl)-3-carboxy(carbalkoxy)methylbenzimidazolium halides and their 2-imin
