A simple and convenient approach was suggested for the synthesis of 4-amino-2-aryl-2H-pyrimido[1,2-b][1,3]benzimidazole-3-carbonitriles or -benzothiazole-3-carbonitriles through a three-component reaction of 2-aminobenzimidazole or 2-aminobenzothiazole, a
Chemoselective synthesis of 4-oxo-2-aryl-4,10-dihydropyrimido [1,2-a][1,3]benzimidazol-3-yl cyanides via [3+3] atom combination of 2-aminobenzimidazole with ethyl-α-cyanocinnamoates
