The disclosure is directed to compounds and methods for preparing purified macrocyclic peptide using “catch-release” methods. These methods comprise reacting a free amino group of a resin-bound linear peptide with an azide- or alkyne-functionalized cap to form a resin-bound capped linear peptide having an azide- or alkyne-functionalized cap; cleaving the capped linear peptide from the resin to form a free capped linear peptide having an azide- or alkyne-functionalized cap; reacting the free capped linear peptide having an azide-functionalized cap with an alkyne-functionalized catch resin, or reacting the free capped linear peptide having an akynyl-functionalized cap with an azide functionalized catch resin, to form a catch-resin bound capped linear peptide; reacting the catch-resin bound capped linear peptide under conditions sufficient to effect macrocyclization of the linear peptide and release of the macrocyclic peptide from the catch resin.
