Formation of Functionalized 2H-Azirines through PhIO-Mediated Trifluoroethoxylation and Azirination of Enamines

Organic Letters, 2013
A variety of enaminones and enamine carboxylic esters were converted to trifluoroethoxylated 2H-azirines through reactions with PhIO in trifluoroethanol (TFE). The cascade reaction is postulated to proceed via a PhIO-mediated oxidative trifluoroethoxylation and a subsequent azirination of the α-trifluoroethoxylated enamine intermediates.

Characterization of Azirine and Its Structural Isomers

The Journal of Physical Chemistry A, 2018
The structures and spectroscopic properties of azirine (C2H3N), a nitrogen-containing three-membered cyclic molecule, and its isomers were studied with state-of-the-art ab initio quantum chemical methods. Azirine is isomeric with methyl cyanide (CH3CN) and methyl isocyanide (CH3NC)-both observed in the star-forming regions of Sgr B2.

Enantioselective Reaction of 2H‐Azirines

Chemistry – An Asian Journal, 2019
Abstract2H‐Azirines are useful precursors for the synthesis of a variety of chiral aziridine and amine derivatives with a range of biological activities. Owing to the ring strain and the presence of a C=N double bond, 2H‐azirines are more reactive than other types of ketimine, and undergo a range of enantioselective reactions, including reduction and ...

Azirines, aziridines and related compounds

1991
Publisher Summary This chapter reviews the most significant advances in azirine and aziridine chemistry. Synthesis of 2H-azirines is discussed. The thermal rearrangement of a vinylazide can proceed by 3,5 ring closure with elimination of N2 to afford a 2H-azirine.
