Abstract A series of unactivated racemic and chiral aziridine-2-phosphonates were synthesized by modified Gabriel-Cromwell reaction. Ring opening reaction of the synthesized phosphonates by gaseous HCl provided access to a wide range of biologically interesting novel β-chloro-α-aminophosphonates. All reactions toward each of the above-mentioned products can be conducted regioselectively in high yields
