Application of bis(oxazoline) in asymmetric β-amination of chalcones†
Abstract
An effective enantioselective β-amination of chalcones with N-bromosuccinimide into β-imidoketones using a bis(oxazoline) ligand is described. A wide variety of β-imidoketone derivatives containing various functional groups can be obtained with high enantioselectivities. The products are highly valuable molecules regarding their vast applications as building blocks of drugs and biologically active compounds.
