Abstract
A biodegradable catalyst based on natural deep eutectic solvents (NaDESs) designed from Betaine and natural acids (Betaine: Citric Acid: H2O) with a molar ratio of (1:1.5:1) has been utilized in one-pot multi-component reaction for the synthesis of Isoxazol-5-ones derivatives in a mild, green and efficient manner. The reaction was carried out under different conditions that are, at 400C, ultrasonic and microwave. The developed method provided many advantages, including an excellent yield of up to 98% in a shorter reaction time, avoiding the use of toxic solvents and an easy handling process. Additionally, the use of NaDESs enabled the conservation of resources due to their simple preparation. The developed process adheres to the requirements of green chemistry by employing a bio-sourced and recyclable catalyst.
期刊介绍：
The purpose of Polycyclic Aromatic Compounds is to provide an international and interdisciplinary forum for all aspects of research related to polycyclic aromatic compounds (PAC). Topics range from fundamental research in chemistry (including synthetic and theoretical chemistry) and physics (including astrophysics), as well as thermodynamics, spectroscopy, analytical methods, and biology to applied studies in environmental science, biochemistry, toxicology, and industry. Polycyclic Aromatic Compounds has an outstanding Editorial Board and offers a rapid and efficient peer review process, as well as a flexible open access policy.
