However, it has been reported that two N-Boc 2-substituted aziridines led to the same γ-(Boc-aminomethyl)-γ-lactone through a fully stereoselective Lewis acid catalyzed intramolecular ring-opening process quite close to that intended here on our aziridines 6: Ho, M.; Chung, J. K. K.; Tang. N. Tetrahedron Lett. 1993, 34, 6513-6516.

The absolute configurations of 2e and 2f were assigned by comparison of the sign of the specific rotation of 2e with that of an authentic sample of its enantiomer (compound 570559 in 2007-08 Aldrich catalog, in which the configuration at the N chiral center is not specified).
