2,3-Dihydroperimidines are dehydrogenated smoothly by sodium pyrosulfite in refluxing aqueous alcohol, as a result of which the corresponding perimidines are formed in high yields.The reaction of 1,8-naphthalenediamine with the aldehydic forms of sugars gives 2-polyhydroxyalkyl-2,3-dihydroperimidines, which are also aromatized by sodium pyrosulfite to give the corresponding 2-polyhydroxyalkylperimidines in high yields.
