1. INTRODUCTION The chemistry of three-membered ring heterocycles has played a
dominant role in the history of organic synthesis. 1 Countless classic and modern protocols …

Since the discovery of organic azides by Peter Grieß more than 140 years ago, numerous
syntheses of these energy‐rich molecules have been developed. In more recent times in …

Abstract 2H-Azirines are versatile building blocks for the preparation of various nitrogen-
containing heterocycles. Seven years ago the comprehensive review on azirine chemistry …

Seit der Entdeckung der organischen Azide vor über einhundertvierzig Jahren durch Peter
Grieß wurde eine Reihe von Synthesen für diese energiereichen Moleküle entwickelt. In …

2H-Azirines, compounds with a three-membered ring, consisting of two carbon atoms and
one nitrogen atom with a C double bond N double bond, are the most strained nitrogen …

A novel [3+ 2] cycloaddition/oxidative aromatization sequence via visible light-induced
photoredox catalysis is disclosed. It provides a general synthetic route to 2, 4, 5-trisubstituted …

Abstract 2H‐Azirines are easily synthesized from the corresponding ketones and, despite
possessing a C N bond embedded in a strained three‐membered cycle, they are …

A novel method for convenient access to CF3‐containing azirines has been developed, and
involves a copper‐catalyzed trifluoromethylazidation of alkynes and a photocatalyzed …

A novel and efficient Fe-catalyzed radical cycloaddition of 2 H-azirines and enamides for the
synthesis of substituted pyrroles has been developed. The radical cycloaddition reaction …

An efficient rhodium-catalyzed synthesis of 2 H-azirines and pyrroles has been developed.
Novel rearrangement of α-oximino ketenes derived from α-diazo oxime ethers provides 2 H …
