Some New Pyrido[2,3-d ]pyridimines and their Nucleoside of Biological Importance
Chalcones (I) reacted with malanonitrile and ammonium acetate yielded 2-amino-3-cyano-4,6-disubstituted pyridines (II) in excellent yield. 4-Amino-5,7-disubstituted pyrido [2,3-d]pyrimidine-2(1H)-thiones (III), 4-amino-5,7-disubstituted pyrido[2,3-d]pyrimidines (IV) and 4-imino-3,5,7-trisubstituted...
