Cyclic oligoamides and alternating oligo(amide-ester)s have been prepared by a novel polymer supported method in yields ranging from 28-48%. In the case of the synthesis of cyclic oligo(undecanamide-undecanoate)s the cyclics obtained ranged in size up to ones having at least 288 ring atoms. The polymer beads recovered at the end of the syntheses contained material accounting for 25-48% of the bound starting monomers. The nature of this material is unclear but a significant fraction may be large cyclics wrapped round the network. Experiments to clarify this last point are in hand.
