A unique binaphthyl strapped iron-porphyrin catalyst for the enantioselective epoxidation of terminal olefins.
A new chiral binaphthyl-strapped iron-porphyrin 4 b that exhibits unprecedented catalytic activity toward the enantioselective epoxidation of terminal olefins was synthesized. Typical enantiomeric excesses (ee) of 90 % were measured with a maximum of 97 % for the epoxidation of styrene, whereas the turnover numbers (TON) averaged 16000.
