Synthesis 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 ...

Phosphinic and Phosphonic Acids I: Protonation and Complex Formation Equilibria of Some Substituted Ethane-1,1,2-tris-(P-methyl-phosphinie Acids)

Oligophosphonic and -phosphinic acids roused significant interest as complexing agents and gained importance in many fields of practical chemistry. Particular attention was drawn towards molecules having two or more phosphonic or phosphinic acid substituents in vicinal and/or preferably geminal positions attached to the ethane fragment. Novel synthetic procedures [1 -4 ] led to structures relat...

New strategy for the synthesis of functionalized phosphonic acids

Various approaches leading to mono-, diand poly-functionalized phosphonates as well as phosphoryl heterocycles were reported for the systematic study of relationship between chemical structure and biological activities of this most important class of organophosphorus compounds. Introduction Functionalization of phosphonic acid molecules opens enoi-nious possibilities of structural variation of ...
