The orientation in the base-catalyzed rearrangement of 3-substituted jV-(aryloxy)pyridinium tetrafluoroborates (5) to 2or 6-(2-hydroxyaryl)pyridines has been studied. A 3-methyl group directs exclusively to the 6-position while inductively electron-withdrawing substituents (Cl, Br, I, OMe, C02Me, COMe) direct mainly, if not exclusively, to C-2. The phenols derived from 3-C02Me derivatives cyclize spontaneously to the substituted pyrido[3,2djcoumarins (8) in useful yields, and that from the 3-COMe compound gives 10-hydroxy-10-methyl-6-nitropyrido[2,3-d]benzopyran (9). The 3-halo-2-(2-hydroxyaryl)pyridines cyclize to benzofuro[3,2-b]pyridines (10,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
