ChemInform Abstract: Organocatalytic Access to Enantioenriched Dihydropyran Phosphonates via an Inverse-Electron-Demand Hetero-Diels-Alder Reaction

The presented reaction, catalyzed by a bifunctional squaramide containing aminocatalyst is applicable to aliphatic, as well as aromatic α,β‐unsaturated acyl phosphonates bearing electron‐withdrawing or donating substituents to give good to high yields and good enantioselectivities.
