Synthesis of symmetric bis(imidazole-4,5-dicarboxamides) substituted with amino acids

A series of symmetric bis(imidazole-4,5-dicarboxamides) (bis-I45DCs) were prepared with amino acid esters and a variety of linker groups. The critical pyrazine intermediates, substituted with amino acid esters, were synthesized by stoichiometric control o
