Aiming high: The title reaction for the synthesis of tertiaryα‐hydroxyketones is reported. Protected 1,2‐enediol carbonates, the starting materials, were accessed from simple and readily available enol carbonates. Highly functionalized tertiaryα‐hydroxyketones can be obtained in high yield with excellent enantioselectivity using this method (see scheme).
