Synthesis of trifluoromethylated 2H-azirines through Togni reagent-mediated trifluoromethylation followed by PhIO-mediated azirination

Beilstein Journal of Organic Chemistry, 2018
The reaction of enamine compounds with the Togni reagent in the presence of CuI afforded β-trifluoromethylated enamine intermediates, which were converted directly to biologically interesting trifluoromethylated 2H-azirines by an iodosobenzene (PhIO ...

Multicomponent Synthesis of Fluorine‐Containing Bioactive Compounds and Drugs

European Journal of Organic Chemistry, Volume 28, Issue 38, October 15, 2025.
Multicomponent reactions are robust synthetic tools to assamble complex polyheterocycles and other interesting molecular architectures with potential application in medicinal chemistry, including their fluorine‐containing analogues. Fluorine atoms placed strategically into bioactive molecules often enhance essential pharmacokinetic parameters like ...

Azirines. III. The Preparation of Azirine Derivatives by the Base-Catalyzed Rearrangement of Quaternary Hydrazones [PDF]

Bulletin of the Chemical Society of Japan, 1968
Abstract An attempt to prepare azirines by the base-catalyzed rearrangement of some quaternary hydrazones gave the corresponding azirine derivatives. Namely, 2-phenyl-3-methylazirine was obtained by the treatment of propiophenone dimethylhydrazone methiodide with potassium t-butoxide, but treatment with sodium isopropoxide gave 2,5 ...

2H-Azirines as electrophiles

, 2011
2H-Azirines have shown an unusual potential to synthesise aziridines and other types of compounds. Many functionalized aziridines can be produced by addition of O-, S-,N-, C-nucleophiles and hydride to 2H-azirines. This review is designed to give an overview of the reactivity of 2H-azirines as electrophiles along the years and their usefulness in the ...
