The synthesis of the pyrido[4,3-d]pyrimidine congeners (7 and 8) of inosine and adenosine from the known precursor 3-dimethylamino-2-(2,3-0-isopropylidene-5–0-trityl-D-ribofuranosyl)acrylonitrile (10) is described. The synthetic sequence involves a

A specific and efficient synthesis for 3-(β-D-ribofuranosyl)uracil, isouridine (1), has been devised. Starting with the easily accessible 1-(β-D-ribofuranosyl)-1,2-dihydropyrimidin-2-one (3b) the C-6 carbonyl function of isouridine was built via fo

Direct stannic chloride catalyzed C-glycosylation of N-formyl-4-amino-3-carboalkoxy thiophenes with 1- O -acetyl-tri- O -benzoyl-β- D -ribofuranose, followed by annelation of a fused pyrimidone ring upon treatment with ammonia, constitutes a short a

Several novel 2,4,6-trisubstituted thieno[3,2-d]pyrimidines were synthesized from the hitherto unknown 3-amino-5-methyl-(or 5-phenyl)thiophene-2-carbonitriles 7 and 8. o-Aminonitriles 7 and 8 were obtained in a single step by conjugate addition of me
