Organoiodine-Catalyzed Enantioselective Alkoxylation/Oxidative Rearrangement of Allylic Alcohols.

An enantioselective catalytic alkoxylation/oxidative rearrangement of allylic alcohols has been established by using a Brønsted acid and chiral organoiodine. The presence of 20 mol % of an (S)-proline-derived C2 -symmetric chiral iodine led to enantioenriched α-arylated β-alkoxylated ketones in good yields and with high levels of enantioselectivity (84-94 % ee).
