Intramolecular cyclopropanation of unsaturated terminal aziridines.
Regio- and stereoselective deprotonation of bishomoallylic terminal N-Bus (Bus=tert-butylsulfonyl)-protected aziridines generate aziridinyl anions that undergo diastereoselective intramolecular cyclopropanation giving trans-2-aminobicyclo[3.1.0]hexanes in good to excellent yields.
