Recent approaches to the synthesis of 2H-azirines

[Figure not available: see fulltext.] 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 derivatives, and radical addition/cyclization of alkynes. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.
