ABSTRACT An efficient, highly product selective, eco-friendly, one-pot multicomponent synthesis of dihydropyrimidine derivatives via Biginelli reaction has been described. The reaction was developed by greener nanoparticle-catalyzed organic synthesis enhancement (NOSE) chemistry and solventfree reaction condition (SFRC) approaches, which helped us in making the procedure greener. The reaction went

A series of tricyclic dihydropyrimidine derivatives were synthesized using a one-pot, three-component Traube-Schwarz reaction in the presence of catalyst Zn(ClO4)(2)center dot 6H(2)O. All the purified compounds were evaluated for their in vitro anticancer activity against three different cancer cell lines such as prostate cancer cells (PO), lung cancer cells (NCI-H1299) and colon cancer cells (HCT116). In vitro DNA-intercalation ability of the compounds was investigated by UV vis absorption spectroscopy, showing the insertion of compound into the DNA base pairs and a strong interaction with the DNA double helix.

one-pot syntheses of benzo[4,5]imidazo[1,2-a]pyrimidine and pyrano[4,3-b]pyran derivatives using L-glutamine functionalized nanoparticles (Fe3O4@SiO2@L-glutamine NPs) undermicrowave irradiation. The organo-nanocatalyst underwent characterization through diverse techniques, including FT-IR, p-XRD, SEM, TEM, EDX, XPS, TGA, and VSM. Microwave irradiation and multicomponent reactions synergistically yield
