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