Abstract

An efficient enantioselective formal Betti reaction between phenols and diaryl ketimines generated in situ from isoindolinone alcohols is described. In a reaction catalyzed by a chiral phosphoric acid, a broad range of ketimines and phenols afforded isoindolinone derivatives comprising a congested quaternary stereogenic center bearing three aryl groups in high yields, and high regioselectivities and enantioselectivities.
