Toward the synthesis of 6-hydroxyquinoline starting from glycerol via improved microwave-assisted modified Skraup reaction
Résumé
An efficient and modified Skraup reaction and Bamberger rearrangement in neat water were developed using nitrobenzene and an inexpensive, abundant and environmentally-friendly glycerol under microwave irradiation conditions was furnish regioselectively to the 6-hydroxyquinoline. The target compound was obtained in 77% yield via efficient domino reaction with a “one pot eleven steps”.
