Several amino acid derived iminodicarboxylicacid monomethylesters have been converted into a small array of amide derivatives. Sequentially, we were using an Ugi reaction of R-amino acids, followed by a mild and efficient amidation. Thus we added to this well-known Ugi scaffold another dimension of diversity, thereby enhancing it is potentially use in the combinatorial and medicinal chemistry of multi component reactions (MCRs) and drug discovery. Synthesis of an exemplary array and pharmacophore features are discussed.
