Open up your chemistry! By using cinchonine‐based trimeric quaternary ammonium salts as catalysts, meso‐aziridines can be ring‐opened, in an enantioselective manner, through nucleophilic addition of the sulfur atom of α‐isothiocyanato imides (see scheme; PG=protecting group). This synthetic method provides an efficient way to access useful chiral β‐aminothiooxazole compounds.
