Sonogashira Reactions

An efficient method is developed for the synthesis of 4-(3-arylprop-2-ynyloxy)-6-methyl-2-(methylthio)pyrimidines via palladium-catalyzed Sonogashira reactions of 4-methyl-2-(methylthio)-6-(prop-2-yn-1-yloxy)pyrimidine with electron-poor aryl iodides in acetonitrile at room temperature. Excellent yields of the products were obtained in reaction times of 9–11 h.

Aryl Iodides

The Cu(I)-catalyzed N,N’-diarylation of natural diamines and polyamines such as putrescine, cadaverine, spermine, spermidine and their homologues is described. Aryl iodides bearing electron-donating and electron-withdrawing groups have been employed in the study. The CuI/2-(isobutyryl)cyclohexanone/DMF catalytic system has found to be more efficient in the diarylation of diamines and spermine while the CuI/L-proline/EtCN system proved to be preferable for the diarylation of other tri- and tetraamines like spermidine, norspermidine and norspermine.
