Significance

The catalytic, enantioselective ring opening of meso-aziridines is difficult considering the unreactive nature and problematic enantiofacial discrimination associated with these substrates. This method, utilizing an in situ formed dinuclear Gd(III) complex and TMSCN as nucleophile generates enantioenriched trans-β-cyanoamines in excellent yields and enantiomeric excesses from a variety of meso-N-acylaziridines.
