1,3-Dipolar cycloaddition reactions of 1-propargyluracils2a–h with the azido derivative3af- forded the corresponding 1,2,3-triazoles4a–h. Hydrazinolysis of the esters4a–hgave the corre- sponding acid hydrazides5a–h. Reaction of5a–hwith carbon disulfide in ethanol afforded6a–h.

The antimicrobial activity of compounds4–6was determined.
