  A facile iterative synthesis of 2,5-terpyrimidinylenes that are structurally analogous to alpha-helix mimics is presented. Condensation of amidines with readily prepared alpha,beta-unsaturated alpha-cyanoketones gives 5-cyano-substituted pyrimidines. Iterative transformation of the 5-cyano group into an amidine allows synthesis of 2,5-terpyrimidinylenes with variable groups at the 4-, 4'-, and 4 ''-positions. These compounds are designed to mimic the i, i + 4, and i + 7 sites of an alpha-helix.

  Alpha-helix mimetics and associated methods of making are provided. These compounds are constructed using a 2,5-oligopyrimidine scaffold. The semi-rigid scaffold holds individual side chain-like residues in orientations that mimic the orientations of side chain residues of an ?-helical protein domain. The new scaffold is easier to make than previous scaffolds and has much more favorable physical properties than previous alpha-helix mimics. The amphiphilic alpha-helix mimetics have application for making libraries and for treating diseases or conditions effected by the inhibition or disruption of interactions with the alpha helix of a protein.
