title: Cu-catalyzed N-arylation of oxazolidinones: an efficient synthesis of the kappa-opioid receptor Agonist CJ-15161.
abstract: An efficient method for intermolecular N-arylation of oxazolidinones using catalytic copper in the presence of a bidentate ligand is reported. The conditions allow the use of copper and can be used to prepare enantiopure N-aryl beta-amino alcohols. A short, scalable synthesis of CJ-15,161 is also reported. The required amines were obtained from the precursor alpha-amino acids or, more conveniently, from the corresponding 1,2-amino alcohols.
