WebHydrogenation over Raney-Nickel proved ineffective. It was found that the reduction of the oxime to the racemic amine 5 could be accomplished in good yield (69%) using zinc-copper couple in warm aqueous ethanol with ultrasonic agitation 8. This novel method for the reduction of oximes is vastly preferable to the aluminum-amalgam reductions ... WebOther clandestine routes, although less popular, which have open literature references utilizing heterogenous catalysis for the synthesis of amphetamine are oxime reduction 12,30-31,35 (Fig 3), nitrostyrene reduction 13,32-33 (Fig 4), 2-keto-oxime reductions 16,36,38 (Fig 5) and hydrazone reduction 23,34 (Fig 6).
