  Novel conjugates of tetrahydropyridothienopyrimidones and carbohydrates of amino acids linked by 1,2,3-triazoles were synthesized After establishing the tetrahydropyridothienopyrimidones ring system by ring closure, propargyl groups were introduced by N-alkylation Cu-catalyzed cycloaddition of the propargyl products with azido group containing hexoses or amino acids gives the corresponding 1,2,3-triazoles in high yields This methodology also allowed attaching two carbohydrate molecules to the tetrahydropyridothienopyrimidone core Interesting dependence of the regioselectivity of the N-propargylation of the pyrimidone ring oil the exocyclic substituent found adjacent to the pyrimidine-N-atom was observed A remarkable case of a non-catalyzed intramolecular [3+2]-cycloaddition of an alkyne with ail azide to a 1,2,3-triazole was observed. which occurred in the solid state at it or below (C) 2010 Elsevier Ltd All rights reserved
