Significance

The authors describe the first examples of a highly stereoselective catalytic direct addition reaction of sulfonylimidates with Mannich-type, Michael-type, and azodicarboxylate acceptors. High anti-selectivity is observed for a large scope of substrates. The synthetic utility of the product is demonstrated through a variety of post-reaction modifications. An example of the direct formation of an α-amino acid derivative is also shown.
