                                    Manganese porphyrin systems carrying cyclodextrin binding groups can regioselectively and stereo selectively hydroxylate bound steroid substrates, using iodosobenzene as oxidant, but hydrogen peroxide and other simple oxidants Such as sodium hypochlorite are not effective in water. Thiol ligands were then added to the catalyst, both covalently attached and hydrophobically bound, and with these ligands hydrogen peroxide was now an effective oxidant. (c) 2005 Elsevier Ltd.
