Abstract

Abstract Synthesis of 2-(2-arylvinyl) thienopyrimidines, by the acid catalyzed condensation of nitriles with thiophene o-aminocarbonyl compounds, the condensation of aldehydes with thiophene o-aminoamides, the base catalyzed condensation of aldehydes with 2- methylthienopyrimidines and by the Wittig condensation of 2-thieno- pyrimidinylmethylphosphonium salts with aldehydes is described. Isomeric 5- ...
