《Pyrazoles. VI. Electron-releasing capacity of the pyrazole ring》 was published in Journal of Heterocyclic Chemistry in 1969. These research results belong to Wijnberger, C.; Habraken, Clarisse L.. Category: pyrazoles-derivatives The article mentions the following:
Uv and 1H N.M.R. spectral data and C : O frequencies of some methylpyrazoles containing in the 3-, 4- or 5-position, a formyl-, acetyl- or ethoxycarbonyl group are reported. These data confirm earlier conclusions that, in particular, the 4-pyrazolyl group acts as an electron releasing group. The syntheses of a number of formyl-, acetyl- and ethoxycarbonyl pyrazoles are described. In addition, some 4-dicyanovinyl- and 4-tricvanovinylpyrazoles were investigated. In the experiment, the researchers used Methyl 1-methyl-1H-pyrazole-4-carboxylate(cas: 5952-93-2Category: pyrazoles-derivatives)
Methyl 1-methyl-1H-pyrazole-4-carboxylate(cas: 5952-93-2) 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.Category: pyrazoles-derivatives
