Sustainable alternative protocols for the multicomponent synthesis of spiro-4H-pyrans catalyzed by 4-dimethylaminopyridine
Green approaches to the synthesis of spiro-4. H-pyrans are reported based on the one-pot and three-component condensation via a domino Knoevenagel/Michael/cyclization sequence. These approaches involve evaluation of the activity of several organocatalysts in water as a reaction media and also under...
