Fourteen new CPP analogues have been prepared with methyl 1-(phenylmethyl) (+/-)-1,2-piperazinedicarboxylate 3 as a versatile synthetic intermediate. Derivatives were evaluated as NMDA ligands by their ability to displace [3H]CPP from rat cortical membranes. The binding affinity of various chain lengths at the N4-position of the CPP analogues, 5a, 5b, and 9a mimics the binding affinity observed for
