Fig. 2. Substrate scope for the decarboxylative radical addition to glyoxylate-derived N-sulfinyl imine 1 to furnish the unnatural α-amino acid derivatives 3. The isolated yields of the products and NMR-yields from the crude reaction mixtures (in parenthesis) are reported (for details, see the ESI†). ^a1 mmol scale reaction. ^bSynthesized from the 3x-2 β-diastereomer of 3x (see the ESI†).
