Aziridine derivatives

Aziridination of γ,δ-Dibromoethyl-2-pentenoate with Primary Amines: Extension
the Gabriel—Cromwell Reaction. — Reaction of the model primary amines (II)
44- 114 of
with dibromide (I) reveals that formation of aziridines (III) via Gabriel—Cromwell reaction proceeds with optimized yields in the presence of DBU rather than triethylamine.
These findings allow the conversion of nucleoside (IV) to the desired aziridine (V).
Interestingly, the use of triethylamine in the latter reaction produces the vinyl bromide
(VI). — (WELLER, R. L.; RAJSKI*, S. R.; Tetrahedron Lett. 45 (2004) 30,
