Green Synthesis of New Derivatives of Pyrrolopyrimidine by Employing Cu@KF/Clinoptilolite NPs: Study of Antioxidant Activity

Abstract

In order to create Pyrrolo pyrimidine derivatives, multicomponent reactions involving butanoates, aldehydes, guanidine, activated acetylenic compounds, and ethyl bromopyruvate were carried out in water at room temperature with catalytic amounts of Cu@KF/CP NPs as a high-performance catalyst. Additionally, experiments involving the reducing power of ferric ions and radical trapping by DPPH were conducted to investigate the antioxidant capacity. As a result, the produced compounds exhibit excellent DPPH radical trapping and good ferric ion reduction capacity. The current method offers advantages including good reaction yield, green media, and simple product and catalyst separation.
