Microwave-induced Reactions for Pyrrole Synthesis

Abstract

Abstract: Heterocycles are organic compounds, the most important pharmaceutical skeleton widely distributed in nature. Many of them possess medicinal as well as pharmacological activities. Pyrroles are well-known five-member-privileged scaffolds with pharmaceutical potential. Pyrrole is the component of complex macrocycles, including porphyrins of heme and chlorophylls. Nowadays, the development of microwave-supported synthetic strategies for such biologically relevant heterocycles is an important objective. Microwave-induced pyrrole synthesis has become an environmentally benign route in organic transformation with reduced reaction time and high yields. This mini-review focuses on the eco-friendly microwaveinduced synthesis of pyrroles, their derivatives, and their potential pharmacological applications, covering literature up to 2022.
