Aziridines undergo ring opening readily with various thiols in the presence of polyethyleneglycol (PEG) to afford the corresponding β-amino sulfides in high yields with good regioselectivity under mild and neutral conditions. The PEG can be recovered and reused.

A simple and efficient synthesis of beta-aminosulfides has been introduced by ring opening of aziridine rings with aromatic thiols in the presence of zirconium(IV) chloride under solvent-free conditions at room temperature.
Enantioselective desymmetrization of meso-aziridines with aromatic thiols catalyzed by chiral bifunctional quaternary phosphonium salts derived from α-amino acids
Desymmetrization of meso-aziridines with aromatic thiols was realized by using alpha-amino acids-derived chiral quaternary phosphonium salts catalysts to provide chiral beta-amino sulfides with high yields (up to 99%) and in moderate enantioselectivities (up to 70%).
