An efficient synthesis of carbamate analogues of the NRTI compound stavudine, has been achieved in five steps starting from commercially available thymidine. The synthesis involves conversion of thymidine into stavudine followed by condensation with carbaimidazole derivative obtained from various aromatic and heterocyclic amines in dimethylformamide solvent. The analogues thus obtained were further purified by crystallization to furnish analytically pure products. Examination of biological activity of these carbamate derivatives of stavudine showed that they inhibited HIV replication only at micro-molar concentrations.

Pharmaceutical Applications

Triazolopyridines are a family of compounds that, owing to their biological activity, have many pharmaceutical applications. In this study, 3-(pyridine-4-yl)-[1,2,4]triazolo[4,3-a]pyridine and 6-bromo-3-(pyridine-4-yl)-[1,2,4]triazolo[4,3-a]pyridine were synthesized by using the chlorinated agent NCS for hydrazones under very mild conditions. The characterization of these compounds was achieved by 1H NMR, 13C NMR, FTIR, MS and X-ray diffraction. The compound 3-(pyridine-4-yl)-[1,2,4]triazolo[4,3-a]pyridine was crystallized in the monoclinic space group P 21/c with a = 15.1413(12), b = 6.9179(4), c = 13.0938(8) Å, β = 105.102(6)°, V = 1324.16(16)Å3, Z = 4, and R = 0.0337. Also compound 6-bromo-3-(pyridine-4-yl)-[1,2,4]triazolo[4,3-a]pyridine was crystallized in the monoclinic space group P 21/c with a = 14.3213(11), b = 6.9452(4) (4), c = 12.6860(8)Å, β = 100.265(6)°, V = 1241.62(14)Å3, Z = 4, and R = 0.0561.
