Facile synthesis of stapled, structurally reinforced peptide helices via a photoinduced intramolecular 1,3-dipolar cycloaddition reaction.

ABSTRACT: We report the first use of a photoinduced 1,3-dipolar cycloaddition reaction in "stapling" peptide sidechains to reinforce a model peptide helical structure with moderate to excellent yields; the resulting pyrazoline "staplers" exhibit unique fluorescence useful in a cell permeability study.
