Diels–alder reactions of alkyl 2H-azirine-3-carboxylates with furans [PDF]
, 2001 Methyl 2-(2,6-dichlorophenyl)-2H-azirine-3-carboxylate 1 and furan give the aziridine 2 by a Diels–Alder cycloaddition reaction. The hydrolysis of compound 2 leads to a dihydrofuranol 11 by cleavage of a C–N bond.

Microwave-assisted regioselective ring opening of non-activated aziridines by lithium aluminium hydride [PDF]
, 2010 A new synthetic protocol for the LiAlH4-promoted reduction of non-activated aziridines under microwave conditions was developed. Thus, ring opening of 2-(acetoxymethyl)aziridines provided the corresponding beta-amino alcohols, which were then used as ...

Continuous multistep synthesis of 2-(azidomethyl)oxazoles
Beilstein Journal of Organic Chemistry, 2018 An efficient three-step protocol was developed to produce 2-(azidomethyl)oxazoles from vinyl azides in a continuous-flow process. The general synthetic strategy involves a thermolysis of vinyl azides to generate azirines, which react with bromoacetyl ...

Stabile Zink-Komplexe von 3-Amino-2H-azirinen
CHIMIA, 1978 3-Dimethylamino-2,2-dimethyl-2H-azirine (4a), which is known to react easily with Brönsted acids and electrophiles, forms a stable complex 5a with ZnBr2. In contrast to all other reactions of 4a, the three-membered ring in this complex is preserved. The
