The synthesis of several amphiphilic, nonpeptidic scaffolds that mimic the presentation of i, i + 3 or i + 4, and i + 7 residues of a peptide alpha-helix is described. The approach uses a pyridazine core, and the synthesis involves only a few steps and minimizes the number of C-C bond-forming reactions. The versatility of the synthesis makes it suitable for the preparation of small libraries of low
