The invention provides an improved method of macrocyclization of peptidomimetics, as measured by isolated yields and product distribution, which comprises substitution of one or more of the backbone amide C=O bonds with a turn-inducing motif. The method is general with enhancements seen across a range of ring sizes (e.g. tri-, tetra-, penta- and hexapeptides). Specifically, the invention provides a peptidomimetic macrocycle comprising a carbonyl bioisosteric turn-inducing element having the structure: (I) wherein X is a heteroatom; and wherein R1 to R6 are each independently selected from alkyl, aryl, heteroaryl and H.

of metabolic degradation in most cases. The incorporation of an oxetane into an aliphatic chain can cause conformational changes favoring synclinal rather than antiplanar arrangements of the chain. Additionally spirocyclic oxetanes (e.g., 2-oxa-6-aza-spiro[3.3]heptane) bear remarkable analogies to commonly used fragments in drugdiscovery, such as morpholine, and are even able to supplant the latter

Solid-phase peptide synthesis (SPPS) is used to create peptidomimetics in which one of the backbone amide C═O bonds is replaced by a four-membered oxetane ring. The oxetane containing dipeptide building blocks are made in three steps in solution, then integrated into peptide chains by conventional Fmoc SPPS. This methodology is used to make a range of peptides in high purity including backbone modified
