Microwave spectrum of 3-methyl-2H-azirine

Journal of Molecular Structure, 1997
Abstract The microwave spectrum of 3-methyl-2H-azirine produced by pyrolyzing N -chloro-2-methylaziridine was observed. This new, unstable molecule was identified based on a comparison of observed molecular constants and those determined by an ab initio MO calculation. The rotational constants are A = 22338.04(4), B = 6618.622(9), and C = 5464.

Recent approaches to the synthesis of 2H-azirines

Chemistry of Heterocyclic Compounds, 2019
The most recent (2013–2018) synthetic approaches toward 2H-azirine derivatives are summarized and discussed. This minireview covers the latest examples on the synthesis of 2H-azirines that can be gathered in five distinct categories: the Neber approach, decomposition of vinyl azides, ring contraction of isoxazoles, oxidative cyclization of enamine ...

Nitrile Ylides and Nitrenes from 2H-Azirines

1982
2H-Azirines represent versatile substrates which can serve as useful precursors for the synthesis of other heterocyclic rings.1–7 An unusual feature of this three-membered heterocyclic ring is that it is susceptible to attack by both electrophilic and nucleophilic reagents.7 In addition, the 2π electrons present in the ring are known to participate in ...
