| Abstract: | An optimized synthesis of cisendo 3-propenamide-zinc mesotetraphenylprophyrin bearing a C protected dipeptide is described. The choice of zinc is based on its ability to participate in pentacoordinated derivative formation. Some spectral properties of such a derivative bearing a conformational stabilised zinc-sulfur bond (the sulfur atom belongs to a cysteine residue) are described. |
