protium for deuterium under acidic and basic conditions: however, they failed to undergo clean bromination or aldol condensation. Autoxidation of alkyl groups at this position provided ready access to pteridines substituted with carbonyl groups at C-6. 6-Formyl derivatives underwent Wittig-type reactions to yield 6-aralkylidene compounds that are potential inhibitors of dihydrofolate reductase. Alkylation
