First example of the intermolecular palladium-catalyzed asymmetric allylic alkylation of hydroxyacrylates: Synthesis of all-carbon alpha-aryl quaternary aldehydes
A set of acyclic all-carbon alpha-aryl quaternary aldehydes was synthesized by intermolecular palladium-catalyzed asymmetric allylic alkylation (Pd-AAA). Hydroxyacrylates were used as unprecedented nucleophilic counterparts instead of widely used ketone substrates. This produced a very rare all-carbon quaternary aldehyde. Chiral ligand (R,R)-L3 was found to be optimal in this Pd-AAA reaction and provided good to excellent yields (75-99%) and enantioselectivities (75-94%) with a range of analogs.
