Construction of a Chiral Coordination Polymer with Amphiphilic Cavities for Enantioseparation of β-Nitroalcohols

Ruonan Wu, Yuyang Zhong, Siyu Tu, Meijuan Fan et autres

While the enantiomeric separation of β-nitroalcohols from racemic mixtures is paramount to the manufacture of enantiopure pharmaceuticals, developing chiral separation materials that resolve these compounds with both high enantioselectivity and broad substrate scope remains a massive challenge. Herein, we report a homochiral …

Photoinduced Cyclization of 2-Alkynylanilines to Access 3-Bromoindole Scaffolds

L Chen, Luomo Li, Yuehua Chen, Yu Lu et autres

Herein, we report a visible-light-driven, photocatalyst-free protocol for synthesizing 3-bromoindoles via tandem cyclization-bromination from readily available 2-alkynyl anilines and ethyl 2,2-dibromo-3-oxobutanoate as the bromine source. This operationally simple method enables simultaneous indole formation and C3-bromination in one step, featuring broad substrate scope, …

Carbene–Ketene Formal [3 + 2] Cycloaddition Enabled by Visible-Light-Induced Dual Photolysis of Diazo Compounds

Longlong Fang, Xiaojian Ren, Tingting Liu, Fengya He et autres

Diazo compounds have long been employed through two distinct reaction pathways: carbene transfer and ketene formation, which rarely intersect within a single reaction environment. Here, we report a visible-light-induced dual photolysis strategy that unifies these divergent pathways by selectively activating two distinct …

Sulfur‐Mediated Microenvironment Modulation of High‐Density Fe‐N 4 Sites for High‐Efficiency Oxygen Reduction and Cryotolerant Quasi‐Solid‐State Zinc‐Air Batteries

Bingxian Chu, Hao Nian, Bing Shao, Yu Lu et autres

Abstract Single‐atom catalysts (SACs) featuring Fe‐N 4 active sites hold significant potential for the oxygen reduction reaction (ORR). However, achieving high‐density Fe‐N 4 active sites while precisely modulating their microenvironment to enhance ORR activity remains a formidable challenge. Here, an S‐mediated strategy …
