The invention relates to the fields of peptide mimetics and pharmacy. The invention provides novel cycle forming linkers and bicyclic peptide mimetics prepared therefrom. The linkers comprise an organic moiety P, leaving groups X1 and X2 at benzylic positions, and a reactive group Q capable of participating in a linking reaction. The organic moiety P contains an aromatic (hetero) cycle, an aliphatic heterocycle comprising a positively charged nitrogen atom, and a neutral nitrogen atom.

peptides containing two cysteines are described. These scaffolds contain a functionality with orthogonal reactivity to be used for labeling and ligation. This is illustrated by the chemicalligation of two dissimilar constrained peptides via oxime ligation or strain-promoted azide–alkyne cycloaddition in aqueousmedia.
