Photocatalytic reductive carboxylation of unactivated hydrazones with CO2 [PDF]

Nature Communications
Carboxylation with CO2 is one of the most sustainable strategies for synthesizing carboxylic acids. Particularly, the reductive carboxylation of carbonyl derivatives with CO2 offers a promising route to valuable α-hydroxy acids, α-amino acids and ...

Metal-free sustainable synthesis of oximes and hydrazones from benzyl alcohol and benzylamine [PDF]

RSC Advances
Herein, we report a one-pot synthesis of oximes and hydrazones via oxidative coupling of alcohols and amines with hydroxylamine hydrochloride and hydrazine, mediated by N-bromosuccinimide (NBS) and phenyliodine(iii) diacetate (PIDA), respectively.

Synthesis and antibacterial evaluation of novel hydrazones and bis-hydrazones containing 1,2,3-triazole moiety

Journal of Taibah University for Science, 2022
The current work reports the synthesis of novel hydrazones and bis-hydrazones containing 1,2,3-triazole moiety. Base-assisted aldol condensation of 4-acetyl-1,2,3-triazole 1a (R = NO2) and anisaldehyde (2) gave the corresponding chalcone 3 in 88% yield ...

New possibilities of the functionalization of 6-hydrazino-1,3-dimethyluracils: one-pot synthesis of 5,7-dimethylpyrazolopyrimidine-4,6-dione and 1,3-dimethyl-5-arylidenebarbituric acid derivatives

Chimica Techno Acta, 2021
3-aryl-5,7-dimethylpyrazolopyrimidine-4,6-diones and 5-benzylidene-1,3-dimethylpyrimidine-2,4,6-triones were obtained by heating hydrazones of 1,3-dimethyl-6 -hydrazinouraciles in trifluoroacetic acid (TFA).

Attempts to Access a Series of Pyrazoles Lead to New Hydrazones with Antifungal Potential against Candida species including Azole-Resistant Strains

Molecules, 2021
The treatment of benzylidenemalononitriles with phenylhydrazines in refluxing ethanol did not provide pyrazole derivatives, but instead furnished hydrazones. The structure of hydrazones was secured by X-ray analysis.
