Category: pyrazoles-derivativesIn 1983 ,《Synthesis of 5H-pyrazolo[5,1-c][1,4]benzodiazepine》 appeared in Journal of Heterocyclic Chemistry. The author of the article were Cecchi, Lucia; Filacchioni, Guido. The article conveys some information:
Reaction of 2-O2NC6H4CH2Br with di-Me pyrazole-3,5-dicarboxylate gave di-Me 1-(2-nitrobenzyl)pyrazole-3,5-dicarboxylate which was converted in a few steps to the key intermediate oxopyrazolobenzodiazepine I. I was reduced and dehydrogenated to yield the new tricyclic system pyrazolobenzodiazepine II. In the experiment, the researchers used Methyl 1H-pyrazole-3-carboxylate(cas: 15366-34-4Category: pyrazoles-derivatives)
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.Category: pyrazoles-derivatives
