Redox inversion of helicity in propeller-shaped molecules derived from s-methyl cysteine and methioninol.
One-electron reduction inverts the helicity of copper complexes formed from derivatives of S-methylcysteine and methioninol. The change in conformation of the organic ligand is followed in the exciton-coupled circular dichroism (ECCD) spectra of the complexes.
