RO8191 represents a newly identified small-molecule IFN-α-substitute, which displays potent anti-HCV activity. In this communication, we reported the design and synthesis of two series of imidazo[1,2-α][1,8]naphthyridine derivatives, as RO8191 analogues, via a direct C–H arylation approach. Notably, by adjusting the reaction conditions, we could achieve the two series of analogues via regioselective
