The Paal–Knorr Pyrroles Synthesis: A Green Perspective.

It is still believed that the progress of Green Chemistry necessities to upsurge at a higher pace, if 'molecular science' is to meet the encounters of sustainability. And it is also aforesaid that the revolution of a particular day becomes the new-fangled belief of the next. Therefore, keeping the importance of sustainability as well as green chemistry in mind, herein we report a green perspective of a very well-known named reaction, dubbed as Paal–Knorr pyrrole synthesis. In this document, we have tried to cover some interesting synthetic green approaches belonging to this particular class. We hope that this review article will be very useful to the researchers working in organic chemistry in general and heterocyclic chemistry in particular. [ABSTRACT FROM AUTHOR]
