Synthesis of fully substituted pyrimidines.
A novel approach to the synthesis of fully substituted pyrimidine derivatives armed with an oxy-functionalized acetate chain at the ring is described. The manifold uses amidines as the nitrogen source and activated skipped diynes as the electrophilic reactive partners in a coupled domino strategy. In the first domino reaction, two consecutive aza-Michael additions assemble the six-membered ring...
متن کاملSynthesis of Some Nitrogen Functional Derivatives of 5-substituted-6-azauracil as Biologically Active Compounds
3-Arylhydrazono-2,4-dioxo-4-phenylbutanoates have been prepared by the coupling of benzoylpyruvate with aryldiazonium chlorides. Reactions of the 3-arylhydrazono-2,4- dioxo-4-phenylbutanoates with 1-aminoguanidine, semicarbazide, and thiosemicarbazide gave 5-substituted 2-imino-6-azauracil (3a), 6-azauracil (3b), and 2-thio-6-azauracil (3c), respectively. The analytical data of these compounds ...

Synthesis, antiviral, antituberculostic and antibacterial activities of some novel, 4-(4'-substituted phenyl)-6-(4"-hydroxyphenyl)-2-(substituted imino) pyrimidines.
A variety of novel 4-[(4'-substituted phenyl)-6-(4"-hydroxyphenyl)-2-substituted imino] pyrimidines were synthesized by reacting 4-(4'-substituted phenyl)-6-(4"-hydroxyphenyl)-2-aminopyrimidines with different substituted aromatic aldehydes, with coumarin and with chloroisatin. The 4-(4'-chlorophenyl)-6-(4"-hydroxyphenyl)-2-aminopyrimidines were synthesized by reacting 3-(4'-substituted phenyl)...
