RECENT APPROACHES TO THE SYNTHESIS OF 2H-AZIRINES

Abstract

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.
