often challenging due to the low nucleophilicity of hydroxylgroups, epimerisation, cyclodimerisation, and potential acyltransfer reactions of the ester. Herein, we report a novel macrolactonisation strategy employing a Ag(I)-promoted conversion of peptide thioamides to isoimide intermediates, which undergo site-selective intramolecular acyltransfer to serine/threonine side chains to generate the macrolactone
