An Unusual Oxidative Ring Transformation of Purine to Imidazo[1,5-c] imidazole

(Equation presented) Reevaluation of products derived from 3, 9-dimethyluric acid in a chlorination-reductive dechlorinaton sequence has demonstrated unequivocally that they are not purines. Spectroscopic and degradative evidence, in conjunction with position-labeling NMR studies, revealed an unprecedented oxidative ring transformation pathway involving the key purine-to-imidazo[1,5-c]imidazole rearrangement.

Purines XIV. [1]. Reactivity of 8-Bromo-3,9-dimethylxanthine Towards Some Nucleophilic Reagents

The reactivity of 8-bromo-3,9-dimethylxanthine (6) towards a variety of nucleophilic reagents has been investigated. Nucleophilic displacements take place easily with aliphatic mercaptans and aliphatic alcohols, whereas aliphatic amines required more severe conditions. Prolonged heating of 6 with amines causes a new type of rearrangement from 3,9- to 3,7-dimethylxanthines due to a 1,3-sigmatropic shift of the N(9)-methyl group.
