Regioselective oxidation of steroids by a manganese porphyrin carrying metal coordinating groups.
A manganese porphyrin having four 2,2'-bipyridyl groups on its meso positions was synthesized. In the presence of Cu2+ ions it catalyzes the regioselective oxidation of steroid substrates carrying auxiliary metal coordinating groups.
