Abstract

A highly efficient protocol is reported for the synthesis of chiral β-seleno amines via the ring-opening reaction of aziridines. Under neutral conditions, employing a stable phenyl selenolate specie (PhSeZnBr) and (BMIM)BF4 as solvent, β-seleno amines were obtained in good to excellent yields. Reuse of the ionic liquid was also possible, and four runs were performed with no decrease in the yields.
