2H-Azirines in medicinal chemistry

Chemistry of Heterocyclic Compounds, 2021
The review presents an analysis of studies published in the period 1971–2020 devoted to examination of the biological activity of natural and synthetic 2H-azirine derivatives, their use for bioconjugation, as well as search for some new synthetic methods of structural modification of azirines with the aim of improving their biological activity.

Exploiting 2-Halo-2H-Azirine Chemistry

Current Organic Synthesis, 2004
H-Azirines are the smallest unsaturated heterocyclic compounds containing nitrogen. Despite their strain many stable azirines are known. Due to the high reactivity 2H-azirines have been explored extensively for various synthetic purposes. The ring system occurs naturally in the antibiotics azirinomycin, isolated from Streptomyces auras cultures ...

Alkylation et silylation de 2h-azirines

Tetrahedron Letters, 1985
Resume Alkylation and silylation of 2H-azitines are reported. Methylation of lithiated azirines is always observed at the carbon atom. N- or C-silytated azirines can be obtained depending on the silyl reagents or substrates.

Electronic structures of vinylazide, vinylnitrene and 2H-azirine. Mechanism of the reaction from vinylazide to 2H-azirine

Tetrahedron, 1984
Abstract The mechanism of the conversion of vinylazides into 2H-azirines is examined by use of ab initio MO calculations. It is ascertained that vinylnitrenes have very weak bonds between the vinylazides and nitrogen molecule parts. It seems to decompose readily into the two fragments.

Conical intersections and photoreactions of 2H-azirines

Chemical Physics, 2000
Abstract CASSCF calculations were performed on the nπ * - and ππ * -excited states of 2 H -azirine as well as some alkyl-substituted 2 H -azirines. An S 1 /S 0 conical intersection (CI) was located, through which a direct formation of nitrile ylide can occur.
