MCM-41@Schiff base-Co(OAc)2 as an efficient catalyst for the synthesis of pyran derivatives

Heterogeneous ordered mesoporous silica materials catalyst, MCM-41@Schiff base-Co(AcO)2, reveals high catalytic performance within the synthesis of pyran derivatives using the multicomponent reaction of aldehydes, malononitrile and 2-naphthol (

Efficient synthesis of 2-amino-3-cyano-4H-pyran derivatives via a non-catalytic one-pot three-component reaction

Abstract: A convenient one-pot multi-component strategy was conducted successfully under catalyst-free conditions employing water and PEG-400 as the efficient and cheap promoting medium. Three types and nearly 50 2-amino-3-cyano-4H-pyran annulated derivat

Potassium-Exchanged Zirconium Hydrogen Phosphate [α-Zr(KPO4)2]-Catalyzed Synthesis of 2-Amino-4 H -pyran Derivatives under Solvent-Free Conditions

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.
