α-hydroxy imines possessing synthetically challenging vicinaltetrasubstituted stereocenters. The electrophilicity of the imine and steric effects promoted a face-selective 1,2-allyl migration in the presence of Lewis acidic boronic acids, yielding chiral α-amino ketones with excellent diastereoselectivity. This method was applied to the total synthesis of hapalindole alkaloids.
