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
