The intramolecular Curtiusrearrangement suffers from a high reaction temperature, low yields, tedious product isolation, and difficult scale up. This study presents a room-temperature Curtiusrearrangement that can be novelly driven by the HFIP solvent, followed by light-illuminated intramolecular cyclization. Such a mild reaction allows for the preparation of various fused pyridone derivatives with
We investigated the one-pot synthesis of several fused 2-pyridone ring systems based on a Curtius rearrangement, followed by a microwave-assisted thermal electrocyclization of a 2-aza-6 pi-electron system including isocyanate. We synthesized seven heterocyclic compounds containing a fused 2-pyridone ring. In these results, the one-pot synthesis of fused 2-pyridone ring system 5 from (E)-acrylic acids 1 under microwave irradiation conditions was more effective than the conventional reaction conditions in terms of the yield and the reaction time.
