Abstract
A La(O-iPr)3/(S,S)-TMS-linked-BINOL complex possessing bifunctional Lewis acid and Brønsted base properties in combination with an achiral nucleophilic organocatalyst efficiently promoted a catalytic asymmetric aza-Morita-Baylis-Hillman reaction of unactivated methyl acrylate with a broad range of N-diphenylphosphinoyl imines.
