The reaction of chiral 2-(1-aminoalkyl)aziridines 1 with different thiols, in the presence of BF3·Et2O, is reported. The obtained products were dependent on the structure of the starting amino aziridines 1. Thus, enantiopure (2S,3S)-2-(alkylthio)alkane-1,3-diamines 2 were obtained from aziridines with C-2 substituents with lower steric congestion and partially racemized (2S,3S)-2,3-bis(alkylthio)alkan-1-amines
