Samariumdiiodide catalyzes the Michael addition of aromatic amines onto α,β-unsaturated N-acyloxazolidinones to form β-aminoacid derivatives. Aza-Michael reactions can be followed by an amidation reaction with the aromatic amine, leading to β-aminoamides. β-Amino-N-acyloxazolidinones are selectively obtained with o-anisidine, while amidation reaction is observed with p-anisidine.
