Abstract In this study, 2-amino-6-thioxouracil is utilized as a precursor for the synthesis of novel functionalized and fused pyrimidine heterocycles including tetrazolopyrimidines, imidazolopyrimidines and triazolopyrimidines. Some of the newly synthesized compounds show moderate to good antibacterial and antifungal activities against the tested microorganisms.

2-Amino-4-hydroxy-6-mercaptopyrimidine (II) has been synthesized by condensation of guanidine with methyl ethoxycarbonyl-dithioacetate (I). The structure of the condensation product II has been proved (a) by desulfurization to isocytosine (III), (b) by comparison with a specimen prepared by treatment of 2-amino-4-chloro-6-hydroxypyrimidine (IV) with NaSH.
