Abstract
A one-pot three-component condensation of an aldehyde, malononitrile, and resorcinol has been achieved by ultrasound method. The reaction has been catalyzed by glycine in aqueous medium. This protocol afforded corresponding 2-amino-4H-chromenes in shorter reaction times, high yields and simple work-up procedures with the green aspects by avoiding toxic reagents.
► Development of new synthetic methodology. ► An efficient use of glycine as an organocatalysts. ► Universal solvent as a reaction medium. ► One-pot multi-component synthesis of 2-amino-4H-chromenes. ► Use of alternate source of energy-ultrasound in synthesis of chromenes.
