A chiral iron(III) salencomplex with a chiral photo-switchable phosphate counterion is reported for the sulfoxidation of alkenes in a stereoselective manner. Irradiation with light allows access to either enantiomer of the sulfoxide.
enantioselective sulfoxidation of various sulfides has been achieved by a N,N'-dioxide-iron(iii) complex with 35% aq. H2O2 as the oxidant. The utility of the current method was demonstrated by asymmetric gram-scale synthesis of drug molecule (R)-modafinil. Moreover, a possible working mode was provided to elucidate the chiral induction.
