Abstract
An efficient non-ionic surfactant catalyzed multicomponent synthesis of novel benzylamino coumarin derivatives has been developed from secondary amines, aromatic aldehyde, and 4-hydroxy coumarin via Mannich type reaction in aqueous media. In this Mannich type reaction, surfactant forms stable colloidal medium to stabilize iminium ion which undergoes nucleophilic addition of 4-hydroxy coumarin to give benzylamino coumarin in very good yields.
