A series of 5β-methylprolyl-2-cyanopyrrolidine analogs were synthesized and evaluated as DPP-IV inhibitors, and the duration of their ex vivo activity was assessed. Comparison of their potency and duration of action was done among three different species.

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.
Amino Acid Derivatives That Stabilize Secondary Structures of Polypeptides. 4. Practical Synthesis of 4-(Alkylamino)-3-cyano-6-azabicyclooct-3-enes (Ben Derivatives) as γ-Turn Templates
