A new strategy for the synthesis of cyclic peptoids was developed. The approach is based on the use of consecutiveUgireactions for the assembly of the acyclic peptoid and for the ring closure. Cyclopentapeptoid analogues of the RGD peptides were designed and synthesized using this methodology. The results confirm the versatility and efficiency of the method for the preparation of cyclic oligopeptoids

A small parallel library of peptoid macrocycles with natural-product-derived side chains of biological importance was produced by Ugi-type multiplemulticomponentmacrocyclizations including bifunctional building blocks (Ugi-MiBs). Diverse exocyclic elements of high relevance in natural recognition processes, i.e., all functional amino acid residues (e.g., Cys, Arg, His, Trp) and even sugar moieties
