Introduction of chirality to the remote, open face of a metalloporphyrin through coordination to the metal of a specially designed pendant arm
Chirality has been introduced to a metalloporphyrin by a new approach that involves coordination to the metal of a pendant arm, with the preferred conformation adopted by the resulting chelate ring causing the meso-phenyl group to which the arm is attached to twist and thereby introduce chirality to the remote, open face of the metalloporphyrin.
