- 5,5′-bipyridyl-2,4,6,2′,4′,6′-hexaone derivatives (hydurilic acids): Syntheses, mechanism of C-C-Bond formation and properties of the dimeric barbituric acid derivatives
-
A series of hydurilic acid derivatives (5,5′-bipyrimidinyl-2,4,6,2′,4′,6′-hexaones) including several new derivatives was synthesized from 5,6-diaminouracils. Mechanisms for their formation are proposed and discussed. Furthermore, a new method for the preparation of pyrimidine-2,4,5,6-tetraone-5-oxime derivatives (violuric acids) was found starting from 5-amino-6-nitrosouracils.
