| Abstract: | reaction: see text] Bissulfoximines have been used as chiral ligands in copper-catalyzed enantioselective Diels-Alder reactions between acryloyl-2-oxazolidinones and cyclopentadiene. After optimizing the ligand structure, the metal source, the counterions, and the solvent, products with up to 93% ee have been obtained. |
