Unexpected C–N bond formation via Smiles rearrangement: one pot synthesis of N-arylated coumarin/pyran derivatives

Author affiliations

Abstract

A conceptually new and one-pot method for the synthesis of N-arylated coumarin/pyran derivatives via Smiles rearrangement. The reaction of 4-bromocoumarin/pyran with 2-amino phenols affords O-arylated coumarin/pyran which subsequently rearranges into N-arylated coumarin/pyran under mild reaction conditions in good yields.
