Convergent Total Synthesis of 16β‐Hydroxylpseudobufarenogin

Angewandte Chemie, EarlyView.
We present a novel convergent strategy that integrates Pd/Ag‐promoted Suzuki–Miyaura coupling with Ir‐catalyzed radical‐relay cyclization, enabling the first total synthesis of 16β‐hydroxylpseudobufarenogin. This approach is broadly applicable to the total synthesis of various oxygenated bufadienolides by simply modifying the fragment structures ...

Cobalt‐Catalyzed Intramolecular C─H Silylation of Arenes

Angewandte Chemie, EarlyView.
Direct C─Si bond formation via C─H silylation is an atom‐economical route to organosilanes but is largely limited to noble metals. We report the first cobalt‐catalyzed intramolecular arene C–H silylation enabled by HCo(PMe3)4, which activates Si–H and C–H bonds to form diverse silacycles and silafluorenes in high yields with broad functional‐group ...

Strategies Toward Accessing Enantioenriched (Hetero)Benzo‐Fused 5‐ and 6‐ Membered Rings via Intermolecular Carbometalation

Angewandte Chemie, EarlyView.
The use of transition‐metal catalysts and design of chiral ligands have allowed chemists to access highly functionalized benzofused 5‐ and 6‐ membered rings in high yield and enantioselectivity. A common strategy used relies on an intermolecular carbometalation across alkynes and olefins, usually followed by a subsequent intramolecular carbometalation.

Electrolyte‐Replacement‐Free Continuous Electrocatalytic Desalination Coupled With CO2 Reduction at Record Throughput and Low Cost

Angewandte Chemie, EarlyView.
A continuous electrocatalytic desalination system powered by CO2 electroreduction that eliminates electrolyte replacement through a self‐balancing circulating design. Using a five‐chamber architecture and an efficient cobalt‐based catalyst, it achieves ultrafast salt removal, high CO production efficiency, and stable long‐term operation, offering a ...
