Heterogenization of Shibasaki's Binol/La Catalyst for Enantioselective Epoxidation of α,β‐Unsaturated Ketones with Multitopic Binol Ligands: The Impact of Bridging Spacers

Bridging the gap: Heterogenized Shibasaki's binol/La catalyst is synthesized by a self-supporting strategy through the reactions of multitopic ligands with La(OiPr)3 (see picture). The catalyst shows high activity and enantioselectivity, and can be reused in the asymmetric epoxidation of α,β-unsaturated ketones.
