Synthesis of 2-halo-2H-azirines [PDF]

open access: yesTetrahedron, 2001
Abstract α-Oxophosphonium ylides react with N -chlorosuccinimide, N -bromosuccinimide and N -iodosuccinimide in the presence of azidotrimethylsilane giving the corresponding haloazidoalkenes which were completely converted to the 2-halo-2 H -azirines on heating in heptane.

Diels–Alder reactions of alkyl 2H-azirine-3-carboxylates with furans [PDF]

open access: green, 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.
