Simple one-pot syntheses of indenopyrrolopyrimidines and indolopyrrolopyrimidines were achieved via the cyclocondensation of 6-Aminouracils and, respectively, ninhydrin and isatin in the presence of catalytic amounts of glacial acetic acid. Similarly, 5,6-diaminouracil derivatives were used as starting materials for the synthesis of indenopteridines and indolopteridines via their reaction with ninhydrin and isatin, respectively. The synthesised compounds were evaluated for antitumour activity against a human hepatocellular carcinoma cell line (HepG2), some showing antitumour activity comparable with 5-fluorouracil and imatinib.

The treatment of 1-benzyl-, or 1-methyl-6-chlorouracil (1a,b) with nucleophilic primary amines followed by nitrosation, reduction, formylation and dehydro-cyclisation lead to xanthines 5 and 7. While, the treatment of uracil 8 with aromatic aldehydes 9a-f leads to the formation of dipyrimidinopyridines 10a-f, reaction with formalin and primary amines gives pyrimidopyrimidines 11a-d via double Michael reactions.
