Sažetak
Homolytic substitution reactions with acyl radicals proceed with 2,4-diamino- (VI-VIlI) and 4-amino-2-methylthiopteridines (XXVII-XX IX) selectively at position 7 to give the corresponding 7-acyl derivatives IX-XV and XXX-XXXV, respectively, in moderate to good yields. The ketone character of these new pteridines is demonstrated by carbonyl reactions forming a hydrazone (XVIII) and oximes (XVI, XVII), as well as 7-(1-hydroxyalkyl)- pteridine derivati ves (XIX, XX) on sodium borohydride reduction. Characterization of the newly synthesized compounds has
been achieved by elementary analysis, lH-NMR and UV spectra.
