The fluoroalkene motif as a surrogate of the amide bond: syntheses of AA-Ψ[(Z) and (E)-CFCH]-Pro pseudodipeptides and an Enalapril analogue
摘要:
This work describes the optimization process for the synthesis of pseudodipeptides featuring a proline bound to another amino acid through a fluoroalkene moiety that act as an amide bond surrogate. The synthetic methodology is extended to non-peptidic molecules as demonstrated in the design and synthesis of an Enalapril analogue. (C) 2015 Elsevier Ltd. All rights reserved.

From ethyl-2-oxocyclopentanecarboxylate, we developed an asymmetric synthesis of the fluorinated dipeptide Ala-Ψ[(Z)CFCH]-Pro analogue of the transoid parent dipeptide. The fluorinated pseudodipeptide could be incorporated into various peptides or proteins for conformational, structuralstudies and biological activity studies and could also play a relevant role as an enzyme inhibitor.
