The present invention relates to a new aziridine derivative that is represented herein by general chemical formulae (Ia) or (Ib), and to their preparation method. In the said chemical formulae, R<SUB>2 </SUB>and R<SUB>3 </SUB>can be the same or different, and they are hydrogen, low-quality alkyl or cycloalkyl respectively; R<SUB>4 </SUB>can be selected among hydrogen, alkyl, aryl, or amino protective group; and amino protective group is, for example, (Ph)<SUB>3</SUB>C, and FMOC( 9 -fluorenylmethyloxycarbonyl), alkoxycarbonyl, aryloxycarbonyl, aralkyloxycarbonyl and R<SUB>5</SUB>CO, R<SUB>5</SUB>SO<SUB>2 </SUB>where R<SUB>5 </SUB>is alkyl, aryl or aralkyl.
