context of the use of o-phthaldialdehydes that contain additional substituents in the aromatic ring leading to a detailed analysis of the regioselectivity of the reaction. Eleven monosubstituted o-phthaldialdehydes were synthesised and reacted with alanine. The regioselectivity observed across the eleven substrates led to the design of a disubstituted substrate that reacted with very high control. A gram-scale

The invention described herein is based in part on the discovery of a protein/peptide crosslink, which introduces fluorescent properties, and which has been applied to synthesize analogues of melanocortin and amanitin as choice peptides to be explored in the context of isoindole peptides. Without limitation, it is expected that those trained in the art of peptide synthesis and stapling would appreciate the consequences of this invention such that other peptides of varied length can be similarly constrained by isoindole staples as featured herein.

drugs. Inspired by indole-derived crosslinks found in natural peptide toxins, we employed ortho-phthalaldehydes to create isoindole staples, thus transforming inactive linear and monocyclic precursors into bioactive monocyclic and bicyclic products. Mild, metal-free conditions give an array of macrocyclic α-melanocyte-stimulating hormone (α-MSH) derivatives, of which several isoindole-stapled α-MSH analogues
