(±)-1-amino-2-cyclohexene-1,3-dicarboxylic acid (DHCGA),an unsaturated cyclic analogue of glutamicacid, was prepared from 3-carboxy-4-cyclohexenone by a Bucherer-Bergs reaction. Resolution was performed through coupling with L-leucine and separation of the resulting diastereoisomeric dipeptides. Spectral data, including opticalrotation and circular dichroism of both enantiomers of DHCGA are reported
