A synthetic pathway is presented to a functionalized pseudopeptide molecular platform for use in supramolecular and solution-phase combinatorial chemistry. The platform contains amino acids with quaternary asymmetric centers, the configurations of which are determined by the method of synthesis.
A new class of analogs of natural products useful for supramolecular and combinatorial chemistry is presented. Starting from the structure of natural dolastatins, we have designed and synthesized a series of amino acid-based unnatural rigid platforms having multiple functional groups pointing in the same direction. The stereochemistry of the final product is entirely determined by the chirality...
