Some pyridinium-based functionalized ionic liquids have been used as novel catalysts for the synthesis of 1,2-dihydro-1-arylnaphtho[1,2-e][1,3]oxazine-3-one derivatives via the one-pot multi-component condensation of β-naphthol, aromatic aldehydes, and urea under solvent-free conditions, to afford good to excellent yields ranging from 76 to 91 % within 60 min. A possible mechanism to account for the reaction is proposed.
Protic pyridinium ionic liquid: As an efficient, green and environmentally friendly catalyst for the one-pot synthesis of amidoalkyl naphthol derivatives
Résumé A green and efficient synthesis of amidoalkyl naphthol derivatives via the three-component reaction between aryl aldehyde, 2-naphthol and amide derivatives using 2-methylpyridinium trifluoromethanesulfonate ([2-MPyH]OTf) as a catalyst (5 mol%) is described. This method provides several advantages over alternative procedures such as low cost, under thermal solvent-free green procedure, simple procedure and direct isolation of the products in high yields.
