Microwave Induced Synthesis of Pyrazoline Compounds Containing Substituted Benzyloxy Phenyl Ring System

Abstract

Green chemistry uses highly efficient and environmental benign synthetic procedures to synthesize various bioactive heterocyclic frameworks which are the useful synthons for the synthesis of medicines, plastics, petrochemicals, agrochemicals, cosmetics and many more hence the green chemistry is the need of the day. In this methodology pyrazolines have been synthesized under microwave irradiation¹ using ethanol /alumina. The structures of these compounds were established by elemental analysis and spectral data. The method has several advantages in comparison with conventional synthesis including clean reaction procedure, easy workup, and short reaction time giving excellent yields of product.
