Abstract
Pyrimidines serve as key structural components in chemical frameworks and biological
processes. Several pyrimidine analogues have been produced over the years by means of traditional
methods that necessitated large amounts of solvents, reagents, and, most importantly, additional
time, which has led them to become prohibitive. These procedures are now being replaced with
more cost-effective adaptive methodologies that incorporate one-pot synthesis and greener approaches
involving various green solvents and catalysts. The current review covers a number of
green synthetic techniques, including ultrasound-assisted synthesis, visible light irradiation synthesis,
solvent-free synthesis, catalyst-free synthesis, microwave-assisted synthesis, and green catalyst
synthesis for the synthesis of pyrimidine derivatives. Accordingly, it integrates different strategies
to synthesize heterocyclic pyrimidine analogues in a well-organized manner.
Keywords:
Pyrimidine, green chemistry, microwave irradiation, ultrasound-assisted, visible light irradiation, green catalyst synthesis.
