First Direct Trifluoromethoxylation of Aryl Halides Achieved by the Team of Professor Tang Pingping at Nankai University

The trifluoromethoxy group (-OCF3) is a highly valuable functional group in the design of pharmaceutical and pesticide molecules—its unique stereostructure (perpendicular to the aromatic ring plane) can significantly enhance the binding ability of molecules to biological targets. Additionally, its strong electron-withdrawing nature and high lipophilicity can improve the metabolic stability and cell membrane permeability of … Read more

Academician Wu Lizhu's Significant Review in Chem. Soc. Rev: Inorganic-Organic Hybrid Photocatalysts

With the acceleration of the global energy transition, hydrogen energy, as a clean and efficient secondary energy carrier, is receiving widespread attention. However, over 90% of hydrogen is still produced through traditional methods such as fossil fuel reforming, which is accompanied by significant carbon emissions. Solar-driven photocatalytic overall water splitting technology can directly convert solar … Read more

Direct Activation of Sulfides by C–H Oxidation with Photoexcited Nitroarenes: Formal Manipulations of the C─S Bond

——Green Pharmaceutical Team—— Starfish Review 【Background】The thioether group is widely present in functional materials, drug molecules (such as Montelukast and Diltiazem), and ligand design, but its chemical inertness limits its synthetic applications. Traditional activation of sulfides relies on direct oxidation of sulfur atoms (to form sulfoxides/sulfones), facing bottlenecks such as poor chemical selectivity (prone to … Read more

The Elusive Seven-Membered Ring Tamed! A New Photocatalytic Strategy Achieves Site-Selective Modification

Image source: J. Am. Chem. Soc.Introduction: The seven-membered ring is a crucial structural unit in bioactive compounds, yet its precise synthesis remains challenging compared to smaller ring systems. Traditional methods rely on ring assembly strategies, while direct functionalization of simple cyclic precursors offers a more attractive alternative for substituent structural units. This study by Professor … Read more

Photocatalytic N-Alkylation

From J. Am. Chem. Soc. Hi, everyone! Do you remember the article we shared recently about the activation of alkyl boronic esters by morpholine radicals in the “perfectly flawless” Quasi-Suzuki Coupling? The morpholine radical couples with alkyl boronic esters to generate alkyl radicals and aryl halides. So, can the radicals produced by this pathway be … Read more
