描述:Salen (Mn)-catalyzed asymmetric epoxidation of unfunctionalized olefins. High enantioselectivities and yields are obtained for multiple substrates, especially cis-alkenes. A few applications include the synthesis of the taxol side chain and cis-1-amino-2-indanol. Jacobsen's catalyst has been used in the asymmetric α-hydroxylation of silyl enol ethers as well. Catalyst for the enantioselective epoxidation of a variety of olefins.
