Abstract
7-Hydroxyxanthine has been obtained from the reaction of one of the tautomeric forms of 6-amino-5-nitro-souracil and formaldehyde. Its 7-acetoxy derivative reacts rapidly with nucleophiles in neutral aqueous solutions to yield 8-substituted xanthines. Similar facile nucleophilic substitutions at position 8 are observed with 3-acetoxyxanthine, and an analogous mechanism via a commnn intermediate is proposed.
