Recent Synthetic Methodologies Towards the Synthesis of Pyrazoles

Abstract

Synthesis of pyrazole ring system has attracted a continuously growing interest of synthetic chemists because of its privileged structure and therapeutic values in medicinal chemistry. Since its discovery (by Ludwig Knorr) different methodologies for the construction of this moiety have been reported. In this review, focus has been placed on the development of novel synthetic routes/methodologies involving employment of catalysts, substrates, and so forth, during the recent years to achieve pyrazole based organic compounds via construction of pyrazole ring.
