A practical and versatile method for the synthesis of 1-thio-phytosphingolipid analogs through regioselective nucleophilic ring-opening reactions of phytosphingosine aziridine derivatives with thiols is described. The reactions were carried out with N-acylaziridines and a variety of thiol compounds. Microwave irradiation highly improved the yield of the ring-opening reaction and the intermediate N-acyl
