Iron-Catalyzed Asymmetric Epoxidation of Aromatic Alkenes Using Hydrogen Peroxide

Iron-Catalyzed Asymmetric Epoxidation of Aromatic Alkenes Using Hydrogen Peroxide

Ironing out the wrinkles: Highly enantioselective catalytic asymmetric epoxidation of aromatic alkenes with hydrogen peroxide proceeds smoothly in the presence of a catalyst system consisting of ferric hexahydrate, pyridine‐2,6‐dicarboxylic acid, and the novel chiral ligand 1 in 2‐methylbutane‐2‐ol...

Zusammenfassung:Ironing out the wrinkles: Highly enantioselective catalytic asymmetric epoxidation of aromatic alkenes with hydrogen peroxide proceeds smoothly in the presence of a catalyst system consisting of ferric hexahydrate, pyridine‐2,6‐dicarboxylic acid, and the novel chiral ligand 1 in 2‐methylbutane‐2‐ol solvent at room temperature within 1 h (see scheme; Bn=benzyl).
