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

Heterocyclic HIV-1 protease inhibitors.

[formula: see text] A series of simple heterocyclic HIV-1 protease inhibitors were developed on the basis of size, shape, and electronic complementarity to the active site of the enzyme. The C2-symmetric heterocycles do not contain a transition-state isos
