## Abstract 6โ€Polyhydroxyalkylpteridines are synthesised by oxidation of the corresponding pyrano[3,2โ€__g__]pteridines, the latter ones having been obtained by condensation between 5,6โ€diaminopyrimidines **1a,b** and phenylhydraโ€zones **2aโ€e**. The relative configuration at the chiral centers of th
