Several catalysts have been developed for asymmetric epoxidation. Some of the most notable ones include:
1. Sharpless Epoxidation Catalyst: This involves the use of titanium tetraisopropoxide and (+)-diethyl tartrate for the epoxidation of allylic alcohols. 2. Jacobsen's Catalyst: A manganese-based complex that is effective for the epoxidation of various alkenes. 3. Katsuki-Jacobsen Catalyst: This is a chiral manganese-salen (Schiff base) complex used for high enantioselectivity.
