Copper-catalyzed Synthesis and Antimicrobial Activity of Disubstituted 1,2,3-Triazoles Starting from 1-Propargyluracils and Ethyl (4-Azido- 1,2,3-trihydroxybutyl)furan-3-carboxylate

Abstract

1,3-Dipolar cycloaddition reactions of 1-propargyluracils 2a - h with the azido derivative 3 afforded the corresponding 1,2,3-triazoles 4a - h. Hydrazinolysis of the esters 4a - h gave the corresponding acid hydrazides 5a - h. Reaction of 5a - h with carbon disulfide in ethanol afforded 6a - h. The antimicrobial activity of compounds 4 - 6 was determined
