Unlocking the Continuous Flow Asymmetric Hydrogenation of Olefins Through the Development of a Non‐Deactivating Immobilized Iridium Catalyst

Angewandte Chemie, EarlyView.
We have developed stable, robust, and reusable heterogeneous metal catalysts for an efficient continuous flow asymmetric hydrogenation (AH) of a variety of olefins, far beyond the typical benchmark AH. The products are produced continuously over long periods of time with high catalytic performance (up to 99% ee).

Photoinduced Ring‐Opening Polymerization of N‐Carboxyanhydrides for the Preparation of Cross‐Linked Polypeptide Gels

Angewandte Chemie, EarlyView.
We employ a photochemical approach for ring‐opening polymerization (ROP) of α‐amino acid N‐carboxyanhydride (NCA) monomers to prepare covalently cross‐linked synthetic polypeptide gels using a photobase and light, which offers significant advantages in the synthesis of polypeptides and holds great potential for applications requiring spatial and ...

Dynamic Confinement Approach for High Metal Loading Single‐Atom Catalysts Based on Covalent Organic Frameworks

Angewandte Chemie, EarlyView.
We introduced a new synthetic strategy for the preparation of high metal loading crystalline single‐atom catalysts based on covalent organic frameworks with atomically distributed Pd ions and metal contents of up to 22.2 wt%. Theoretical simulations reveal that the crystalline framework dynamically confines Pd atoms between different binding sites ...

Engineering Fluoroacetate Dehalogenase by Growth‐Based Selections on Non‐Natural Organofluorides

Angewandte Chemie, EarlyView.
We present a high‐throughput selection system to engineer fluoroacetate dehalogenases (FAcDs). By challenging E. coli populations that produce diverse FAcD libraries to grow on non‐natural organofluorides as their sole carbon source, we isolated a panel of FAcD variants with improved activity and altered substrate specificity.
