Enantioselective Reaction of 2H‐Azirines
Chemistry – An Asian Journal, 2019Abstract2H‐Azirines are useful precursors for the synthesis of a variety of chiral aziridine and amine derivatives with a range of biological activities. Owing to the ring strain and the presence of a C=N double bond, 2H‐azirines are more reactive than other types of ketimine, and undergo a range of enantioselective reactions, including reduction and ...

Synthesis and reactions of 1-Azirines
1971Publisher Summary Azirine is the term used to describe a three-membered heterocycle containing one nitrogen atom and one double bond. There are two isomeric azirines (1 and 2), which have been designated by Chemical Abstracts and “The Ring Index,” as 1H- and 2H-azirine, respectively.
