Solvent-Free and Microwave-Assisted Synthesis Enables Formation of Imidazole and Pyrazole Derivatives Through Epoxide Ring Opening [PDF]

open access: yesMolecules
A solvent-free, microwave-assisted approach for the ring-opening reactions of phenyl glycidyl ether with a series of commercially available imidazoles and pyrazoles is described. Microwave irradiation allows reactions to proceed rapidly.

Synthesis of Functionalized 1H-Imidazoles via Denitrogenative Transformation of 5-Amino-1,2,3-Triazoles [PDF]

open access: yesMolecules
An efficient access to novel 2-substituted 1H-imidazole derivatives was developed based on acid-mediated denitrogenative transformation of 5-amino-1,2,3-triazole derivatives available through dipolar azide−nitrile cycloaddition (DCR).

Lower micromolar activity of the antifungal imidazoles on the bacterial-type bifunctional aldehyde/alcohol dehydrogenase (AdhE) in Cryptosporidium parvum and in vitro efficacy against the zoonotic parasite [PDF]

open access: yesInternational Journal for Parasitology: Drugs and Drug Resistance
Cryptosporidium parvum is a waterborne and foodborne zoonotic protozoan parasite, a causative agent of moderate to severe diarrheal diseases in humans and animals. However, fully effective treatments are unavailable for medical and veterinary uses. There

Elucidating the proton transport pathways in liquid imidazole with first-principles molecular dynamics [PDF]

open access: yesJ. Phys. Chem. Lett. 11 (2020) 6156-6163, 2021
Imidazole is a promising anhydrous proton conductor with a high conductivity comparable to that of water at a similar temperature relative to its melting point. Previous theoretical studies of the mechanism of proton transport in imidazole have relied either on empirical models or on ab initio trajectories that have been too short to draw significant ...

Regiodivergent synthesis of functionalized pyrimidines and imidazoles through phenacyl azides in deep eutectic solvents

open access: yesBeilstein Journal of Organic Chemistry, 2020
We report that phenacyl azides are key compounds for a regiodivergent synthesis of valuable, functionalized imidazole (32–98% yield) and pyrimidine derivatives (45–88% yield), with a broad substrate scope, when using deep eutectic solvents [choline ...

The Structure of Biologically Active Functionalized Azoles: NMR Spectroscopy and Quantum Chemistry

open access: yesMagnetochemistry, 2022
This review summarizes the data on the stereochemical structure of functionalized azoles (pyrazoles, imidazoles, triazoles, thiazoles, and benzazoles) and related compounds obtained by multipulse and multinuclear 1H, 13C, 15N NMR spectroscopy and quantum
