The dirhodium(II) tetraacetate catalysed reaction of ethyl diazoacetate with 2,3-dihydropyrrole-2,2-dicarboxylate 5 afforded the useful 2-azabicyclohexane 6.Its conversion into the proline-γ-acetic acid equivalent 9 as well as into the four isomers constituting the 4-(carboxymethyl)proline 13 (16a-19a) whose absolute configuration was established by an alternative asymmetric synthesis of two of them is described.Preliminary data concerning the affinity of compounds 16a-19a for the NMDA site of the NMDA receptor complex are also reported.
