Significance

This paper describes the hetero-­Diels-Alder reaction between Danishefsky-type dienes and ketones to generate dihydropyranone products, which is a significant extension of the previously developed copper-catalyzed aldol reactions. By using the chiral Walphos ligands, the first catalytic enantioselective hetero-Diels-Alder reaction of simple ketones is realized.
