Abstract

Peptide-bridged dicatechols were prepared by a combination of solid- and solution-phase synthesis. The target compounds are potential precursors for constrained metal containing enkephalin analogs. While a simple model compound selectively forms a metallamacrocycle with the cis-molybdenum(VI)dioxo unit, this goal could not be achieved with the corresponding peptide bridged derivatives.
