The Directed Ortho Lithiation of O-Aryl Carbamates. An Anionic Equivalent of the Fries Rearrangement

Article abstract of DOI:10.1021/jo00159a040

Ortho-Lithiated O-aryl carbamates 3 constitute new synthetic intermediates which by treatment with a variety of electrophiles lead to ortho-substituted carbamates 4 and by rearrangement provide salicylamides 6.
