A new and efficient ZnCl2-catalyzed synthesis and biological evaluation of novel 2-amino-3,5-dicyano-4-aryl-6-aryl-aminopyridines as potent antibacterial agents against Helicobacter pylori (HP)

Herein a new and efficient method via ZnCl2-catalyzed direct cyclization of diverse benzylidenemalononitriles and arylamines for one-pot synthesis of novel 2-amino-3,5-dicyano-4-aryl-6-aryl-aminopyridines as potent antibacterial agents is described.
