Several nitroflavone derivatives were synthesized by cyclodehydrogenation of 2'-hydroxychalcones and by the Baker-Venkataraman approach, starting from 2'-hydroxyacetophenones and benzoic acid derivatives. Nitroflavones synthesised by the first synthetic approach were obtained in better global yields than those obtained by the later method. The structures of all new compounds were elucidated by microanalyses, 1D and 2D NMR, IR, and mass spectroscopic measurements.

A series of 4,6-diaryl-2-aminopyrimidines was developed as antiplatelet agents and their potency was evaluated by in vitro assay. Compound 14k was found to be two times more potent than aspirin. These encouraging results could be helpful for the development of new antiplatelet compounds. (C) 2012 Elsevier Masson SAS. All rights reserved.
