Abstract: A KOtBu-promoted [4+2] annulation-dehydration cascade reaction has been developed, enabling the efficient synthesis of diverse 2-pyridone-fused uracils through a vinylogous enolization strategy involving o-quinodimethane (oQDM) dienolate intermediates. This method provides a simple yet robust approach… read more here.
