摘要：

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.
