The Long‐Arm Effect: Influence of Axially Chiral Phosphoramidite Ligands on the Diastereo‐ and Enantioselectivity of the Tandem 1,4‐Addition/Fluorination

Long arm of the law: The long-armed phosphoramidite 1 was used as a catalyst for the title reaction of acyclic alkylidene β-ketoesters with dialkylzinc and fluorinating reagents. The products, containing adjacent carbon- and fluorine-substituted stereocenters, are obtained in high yield as well as diastereo- and enantioselectivity. NSFI=N-fluorobenzenesulfonimide.
