Synthesis and antiviral activity of fluorinated pyrido[1,2-a]benzimidazoles

Abstract

Methods for the synthesis of fluorinated pyrido[1,2-a]benzimidazoles have been developed, and a series of such compounds has been obtained and studied for biological activity. In particular, 5,6-difluoro-2-cyanobenzimidazole (II) was synthesized for the first time using the reaction of 1,2-diamino-4,5-difluorobenzole (I) with cyanoacetic ether. Pyrido[1,2-a… (More)
