Synthesis and Bioactivities of Clopyralid Hydrazide-Hydrazones

Mild Fluorination of Chloropyridines with in Situ Generated Anhydrous Tetrabutylammonium Fluoride

“…This compound was prepared using a modification of a literature procedure . 3,6-Dichloropicolinic acid (12.0 g, 62.5 mmol, 1.0 equiv) was weighed into a 100 mL round bottomed flask equipped with a magnetic stir bar.…”

“…This compound was prepared using a modification of a literature procedure. 14 3,6-Dichloropicolinic acid (12.0 g, 62.5 mmol, 1.0 equiv) was weighed into a 100 mL round bottomed flask equipped with a magnetic stir bar. Absolute ethanol (25 mL) and sulfuric acid (0.5 mL) were added, and a reflux condenser was attached.…”

Studies on New Schiff bases of Benzoxazole: Synthesis, Anticonvulsant and Neurotoxicity Evaluation

“…Now cooled the mixture and transferred into a snow bath, solid formed was filtered and recrystallized in alcoholic condition to get compound (3a). The other molecules (3b-l) were organized in the same way [18][19] .…”

“…The recent statistics shown that hydrazones are the new, promising molecules for clinical therapy of epilepsy [14][15][16][17] . Not only do hydrazones have anticonvulsant potency, but have reported anti-inflammatory and analgesic 18 , antimicrobial 19 and antitubercular [20][21] . In this study, novel hydrazone compounds with pharmacophore will be tested by the standard protocols at different dosage and see whether they reflect high efficacy and even more acceptable health complications.…”

Z′ = 2 crystallization of the three isomeric piridinoylhydrazone derivatives of isosteviol

“…According to literature data, the region of 1500-1750 cm −1 is rather difficult for IR spectra analysis of compounds with pyridinoylhydrazonic fragments. [15][16][17][18][19][20] This is caused by the presence of both the absorption bands for CN and CO groups in this area of spectra, as well as the signals relating to the pyridine moiety. It is not always possible to identify unambiguously each of these signals.…”
