environmentally-benign one-potreaction of salicylaldehyde and malononitrile with various nucleophiles, including indoles, thiols, secondary amines, cyanide and azide were efficiently achieved in choline chloride based deep eutectic solvent (DES). Products distribution of the current green protocol depend on the nature of the nucleophile used in the reaction. The one-potreaction of salicylaldehyde derivatives
