چکیده
In this study, new benzoxazole-linked pyrrolidinone heterocyclic compounds were synthesized by an eco-efficient strategy using substituted benzylamines and 2-aminophenol under ultrasonic irradiation in the presence of a newly designed metal-free deep eutectic solvent (DES). This DES was prepared mixture urea glycine-derived ionic liquid. X-ray diffraction infrared spectroscopy employed to investigate structure liquid characterize DES, respectively. method exhibited key advantages high productivity, short reaction time, simple processing. Moreover, easily separated from mixtures can be recycled for multiple reactions.
