A set of mild aerobic cross-dehydrogenativecouplings of N-heteroarenes with the benzylic C(sp3)–H bond has been achieved by using visible-light-induced photocatalysis. This approach was found to provide a sustainable alternative to Minisci benzylation reactions using readily accessible toluene derivatives as benzylating agents. The unique combination of photocatalysis, bromo radical mediation, and
Fused pyridines of formula (I) and the pharmaceutically acceptable salts thereof have activity as inhibitors of c-Met and may thus be used to treat various diseases and disorders including cancer. Processes for synthesizing the compounds are also described.
