Versatile syntheses of 7-and 8-substituted 7-deazaguanines including N-alkyl derivatives have been developed by identifying selective annulation reactions with 2, 6- diaminopyrimidin-4 (3H)-one as substrate and β-halocarbonyl compounds as electrophiles. A new synthesis of 8-substituted 7-deazaguanines using nitrosoalkenes as electrophiles is described. With some combinations of reactants, furo [2, 3-d] pyrimidines are significant ...
