A high-yielding, one-pot, three-component synthesis of functionalized 2-amino-4H-pyrans from β-dicarbonyl compounds, activated cyanomethylene compounds, and aldehydes, mediated by potassium-exchanged zirconium hydrogen phosphate [α-Zr(KPO4)2], is reported. The protocol shows excellent versatility, as it can be applied to aromatic, aliphatic, or α,β-unsaturated aldehydes under solvent-free conditions.
