Formula: C5H6N2O2In 1976 ,《Modified nucleosides. V. Synthesis of pyrazole nucleosides》 appeared in Zhurnal Obshchei Khimii. The author of the article were Akhrem, A. A.; Garbuz, N. I.; Kvasyuk, E. I.; Mikhailopulo, I. A.. The article conveys some information:
Pyrazole nucleosides I, II (R = Ac, R1 = OEt) were obtained in 52 and 26% yields by treatment of Et acetoxymethylpyrazolecarboxylate with α-D-glucopyranose pentaacetate. Subsequent aminolysis yielded 90% I, II (R = H, R1 = NH2). Analogously obtained were 71 and 11% III, IV (R = Bz, R1 = Ac, R2 = OEt) which were treated with NH3 to give 90% III, IV (R = R1 = H, R2 = NH2). Similar results were obtained by glucosylation of Me pyrazolecarboxylate and by ribosylation of Et 4-acetoxymethyl-3-pyrazolecarboxylate. The experimental part of the paper was very detailed, including the reaction process of Methyl 1H-pyrazole-3-carboxylate(cas: 15366-34-4Formula: C5H6N2O2)
Methyl 1H-pyrazole-3-carboxylate(cas: 15366-34-4) belongs to pyrazoles. Pyrazole derivatives have been reported to exhibit a wide range of applications in medicinal chemistry and pharmacology. A large number of drugs incorporating pyrazole structure have been utilized as partial agonists for nicotinic acid receptors, antidepressants, antimicrobial agents, antiviral agents, and antifungal agents solely or along with the combination of other structural motifs.Formula: C5H6N2O2
