Chalcone-derived pyrimidine is a well-known heterocyclic compound that commonly present in ribonucleic acid (RNA) and deoxyribonucleic (DNA) bio-isosteres. Pyrimidine derivatives are effective both the electronic industry drug industries. This review highlights synthesis of pyrimidines, namely mono-pyrimidine, bis-pyrimidine, fused pyrimidine, symmetric, asymmetric via one-pot two-pot methods. ...

F. Milani Nejad,

On the basis of 102 assigned frequencies to in plane vibrations of pyrimidine, pyrimidine-2-d2, pyrimidine-2, 5-d2, pyrimidine-4,6-d2, pyrimidine-2,4,6-d3 and pyrimidine-d4, 35 valance force field constants including 14 principals and 21 interaction force constants are calculated. New assignments are suggested for n<su...

there has been special interest in the chemistry of quinolone and pyrimidine derivatives due to their diverse biological activities such as anticonvulsant, anti-malarial agents, antibacterial, antiviral, cytostatic, antithelemintic, antigenotoxic, anti-cancer agents. these compounds are also used as targeting delayed-type hypersensivity and anti-convulsant agents. as a part of our research work...

In this research, the interaction of pyrimidine molecule with pristine B12N12 nanocluster is studied in different phases to understand the effect of environment on the electronic properties of the designated adsorption complexes. To this end, the pyrimidine adsorption over B12N12 in the gas phase and water medium is investigated using density functional theory (DFT) at the B97D/6-31+G(d,p) leve...

considerable interest has been focused on the triazole structure, which has been known to possess a broad spectrum of biological activities such as antitumor, anti-inflammatory, antimicrobial, antiviral, and anticonvulsant activities. before this, several heterocyclic compounds containing triazole were synthesized that had shown considerable anticonvulsant activity. as part of our continuous re...

T3P/DMSO is shown to be an effective and mild reagent for the one-pot synthesis of furo[2,3-d]pyrimidine-2,4(1H,3H)-diones from a variety of alcohols. Alcohols are oxidized in situ to aldehydes under mild conditions, which undergo a three-component reaction with N,N'-dimethylbarbituric acid and various isocyanides to afford furo[2,3-d]pyrimidine-2,4(1H,3H)-diones in good yields.
