Catalytic Asymmetric Domino Michael-Henry Reaction: Enantioselective Access to Bicycles with Consecutive Quaternary Centers by Using Bifunctional Catalysts
Domino catalysis: Two consecutivequaternary stereocenters, three functional groups, and four stereogenic centers have been created in the newly developed dominoMichael–Henryreaction (see scheme) employing small amounts of a bifunctional organocatalyst.
