A novel approach to biologically relevant oxazolo[5,4-d]pyrimidine-5,7-diones via readily available diazobarbituric acid derivatives

An alternative route from 1,3-disubstituted barbituric acids to biologically relevant oxazolo[5,4-d]pyrimidine-5,7-diones was developed that features sulfonyl-azide-free (SAFE) diazo transfer and Rh2(esp)2-catalyzed cycloaddition of

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.

Ring closure reactions of azidouracils to oxazolo- and isoxazolopyrimidines [1]

Thermolysis of 6-azidouracils 1 in the presence of polyphosphoric acid leads either to oxazolo[5,4-d]pyrimidine-5,7-diones 5 (by reaction with benzoic acid 2a) or to isoxazolo[3,4-d]pyrimidine-4,6-diones 7 (by reaction with aliphatic carboxylic acids 2b,c
