A method for synthesizing C2 functionalized pyrimidine derivatives by phenylalkyne and pyrimidine disulfide under environmental conditions with good group compatibility is reported. Furthermore, density functional theory (DFT) calculations confirm that it is more advantageous to generate C2-functionalized pyrimidine derivatives.
Efficientoxidative transformation of thiols to disulfides took place in the presence of activated carbon under an oxygen (or air) atmosphere. The present oxidationmethod is available not only for a variety of thiols such as simple aromatic and aliphatic thiols but also for 3,4-dihydropyrimidin-2(1H)-thiones and N-Boc-l-cysteine.
