Nano copper oxide mediated ligand-free C–S cross-coupling and concomitant oxidative aromatization of 4-aryl-3,4-dihydropyrimidin-2(1H)-thione with diaryliodonium salts
摘要:
A wide range of Biginelli 4-aryl-3,4-dihydropyrimidin-2(1H)-thiones undergo ligand-free C-S cross-coupling with diaryliodonium triflates in the presence of CuO nanoparticles with the concomitant oxidative aromatization to form highly substituted 2-(thioaryl)pyrimidine. The nano CuO catalyst can be recycled and reused three times without any significant loss of catalytic activity. (C) 2012 Elsevier Ltd. All rights reserved.

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.
