Methods for the synthesis of polyfunctional 6-substituted pteridines from the corresponding 6-aldehydes are described. Alkene, ester, ketone, amide, cyano, oxime, bromo, methoxy and dihydroxy functional groups have all been introduced principally through improved methodologies for Wittig reactions using 2-thioalkyl-6-formylpteridines as substrates. Further modification of the alkenes derived from the Wittig reactions was difficult but selective conversion to the vic-diol was possible using ligand assisted catalysis with osmium tetraoxide. These methods are a component of an extensive methodology for the preparation of compounds that might serve as modulators of tetrahydrobiopterin activity or as inhibitors of dihydroneopterin aldolase.
