Tile synthesis and isolation of heptakis(6-O- carboxymethyl-2,3-di-O-methyl)cyclomalto-heptaose is described. The method provides a homogeneous product that carl be used as a scaffold for the covalent attachment of a defined number of peptides, lipids, or other compounds in preparing supramolecular assemblies. In this report we describe the addition of tryptophan methyl ester and a 7-residue peptide, H2N-WSLSLSL-CONH2, to the percarboxymethylated cyclodextrin carrier.
