Synthesis of (R)-5-Aminohex-2-enedioic acid and the (+/-)-2-Bromo Derivative as Unsaturated Analogues of the Neurotransmitter Antagonist D-&α-Aminoadipic Acid

5-Aminohex-2-enedioic acid (2), an unsaturated analogue of the neurotransmitter antagonist D-α-aminoadipic acid, has been synthesised by a convenient route using a phase-transfer alkylation of N-diphenylmethyleneglycine ethyl ester.The unsaturated amino acid has been resolved and the absolute stereochemistry of the (-) isomer determined as R by reduction to D-α-aminoadipic acid.A more conventional synthetic scheme failed to yield (2), but led to the preparation of the (+/-)-2-bromo derivative (4) in low yield.
