ABSTRACT
The cyclic dichalcogenides based on the bis(2-chalcogenoethyl)amide structure are latent N,S (SEA, chalcogen = S) or N,Se (SeEA, chalcogen = Se) acyl shift systems. The large difference in the reducing potential between SEA and SeEA dichalcogenides allows their sequential and selective activation by reduction. Based on these concepts, one-pot three or four peptide segment assembly processes were designed, facilitating access to branched or cyclic peptide scaffolds.
