Rapid Access to Conjugated Z,Z,Z‐Trienes

Angewandte Chemie, EarlyView.
Z,Z,Z‐triene: A novel method to facilitate rapid access to the otherwise inaccessible conjugated Z,Z,Z‐triene motif is reported. Abstract Intercepting reactions have recently emerged as an innovative approach in organic synthesis, allowing chemists to harness reactive intermediates to access structures and functionalities that conventional methods ...

A Phenazine‐Based Two‐Dimensional Covalent Organic Framework for Photochemical CO2 Reduction with Increased Selectivity for Two‐Carbon Products

Angewandte Chemie, EarlyView.
The catalytic advantages of covalent organic frameworks (COFs) for sustainable CO₂ utilization have been demonstrated by the photocatalytic reduction of CO₂ by a redox‐active, phenazine‐based COF (Phen‐COF). Phen‐COF efficiently converts CO₂ into formate, oxalate, and carbon monoxide under light irradiation, achieving significantly higher yields than a

Enantioconvergent Deacylative Functionalization toward α‐Quaternary Nitriles

Angewandte Chemie, EarlyView.
An enantioconvergent quaternary‐to‐quaternary synthesis of α‐chiral nitriles has been enabled. By replacing the acyl group with a variety of allyl, propargyl, and benzyl motifs, the functional group swap can convert easily available β‐ketonitriles to assorted quaternary stereocenters en route to bioactive molecules of broad interests.
