Asymmetric α‑Sulfonyl- and α‑Phosphoryl-Oxylation of Ketones by a Chiral Hypervalent Iodine(III)

An enantioselective direct oxygenation of propiophenone derivatives mediated by a catalytic or stoichiometric amount of new chiral non-C2-symmetric iodoarenes­(III) is reported. The reaction gives an easy entry to optically active α-sulfonyl- and α-phosphoryl oxyketones in respectable yields and enantioselectivities.
