The development of a versatile solid phase synthesis of bicyclic polyaza heterocycles including pteridines, purines, and deazapurines is described. The strategy comprises the linking of a pre-formed pyrimidine through a thioether at the 2 or 4 position to a polystyrene resin, the cyclisation of the second ring, and the direct or oxidative cleavage of the product from the resin by nucleophilic substitution. This provides not only for substituent variation in the second ring, but also for variation at the site of cleavage. Limitations in the scope of the methodology are set by the intrinsic reactivity of pyrimidinyl 2- or 4-thioethers which, whilst undergoing ready nitration at C5, are surprisingly difficult to alkylate and acylate.

Pteridines of general formula (I): STR1 in which Y and Z, which can be identical or different, are hydrogen, OH or NH2, and X1 and X2, which can be identical or different, are hydrogen, OH, C1 -C4 alkyl, phenyl, hydroxymethyl or carboxyl, for the preparation of pharmaceutical compositions for treating cognitive pathologies characterized by memory and vigilance disturbances, such as senile dementia of Alzheimer type, multiinfarctual dementia, metabolic encephalopathies, Korsakoff's syndrome, and the consequences of the abuse of certain therapies such as anxiolytic and neuroleptic.
