3-Disubstituted N-phosphorylated aziridines except N-phosphorylated cyclohexenimine (4) do not react under the described conditions. Copper-mediated reaction of 2-phenyl-N-(diethoxyphosphoryl)aziridine (7) with Grignard reagents affords a mixture of regioisomers (8) and (9) but still with the preference of ring-opening at the carbon of lesser substitution.

The invention includes processes for the synthesis of amphetamine, dexamphetamine, methamphetamine, derivatives of these, including their salts, and novel precursors and intermediates obtained thereby, by synthesizing aziridine phosphoramidate compounds in specified solvents at specified temperatures, and then converting to a novel aryl or aryl-alkyl phosphoramidate precursors using an organometallic compound such as a copper salt, where the novel aryl or aryl-alkyl phosphoramidate precursor is then easily converted to the target compounds using known reactions.
