US 10,087,202. Issued October 2, 2018.
Exclusively licensed to Pharmapotheca A from Chemapotheca.
Title: Chiral Aziridine Phosphoramidate Compounds.
Abstract: 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.
