Six-Membered N-ANP-Enabled Tandem Catellani/Buchwald Annulation for the Construction of π-Extended Dibenzocarbazoles

Xue Gong, Lei Tian, S Liu, Chengyuan Liang et autres

We report a Pd/NBE/Cu-catalyzed tandem Catellani/Buchwald annulation for the direct C–H/N–H [3+4] cyclization of carbazoles with aryl iodonium salts. This protocol provides efficient access to a range of π-extended dibenzocarbazole frameworks with broad substrate applicability. The reaction operates through a challenging six-membered …

Enantioselective Synthesis of Polysubstituted Boron-Stereogenic BODIPYs Enabled by Pd/Norbornene Catalysis

LinYang Li, Xue Gong, Zai Kou, Qiang Yan et autres

Boron-stereogenic BODIPYs represent an emerging class of chiral fluorophores with promising applications in materials science and bioimaging; however, their enantioselective synthesis, particularly for multiply substituted variants, remains highly challenging. Herein, we report an enantioselective Catellani desymmetrization strategy that enables efficient access to …

Palladium/Norbornene-Catalyzed C–H/C–H [3 + 2] Annulation of Imidazopyridines with 2-Halobenzoic Acids via Six-Membered Palladacycles

Shilei Liu, Lei Tian, Min Zhang, Chengyuan Liang et autres

Herein we report an unprecedented palladium/norbornene-catalyzed C–H/C–H [3 + 2] annulation of imidazopyridines with 2-bromobenzoic acids, efficiently constructing ring-fused imidazo[1,2- a ]pyridine architectures with excellent functional tolerance. The resulting polycyclic (hetero)aromatic products demonstrate promising potential as fluorescent molecular scaffolds. Mechanistic studies identify …

Bifunctional Metal–Organic Gel for Deep Detoxification of Organophosphorus Nerve Agents through a Cascade Degradation Process

Yi Feng, Zhong Wei Jiang, Xue Gong, Yi Wang

Organophosphorus (OPs) nerve agents, as a class of chemical warfare agents and widely used pesticides, are highly toxic synthetic chemicals that pose severe threats to human health and the environment. However, the current method of detoxifying OPs through hydrolysis cannot completely reduce …

Metal-Free C–H [5 + 1] Carbonylation of 2-Alkenyl/Pyrrolylanilines Using Dioxazolones as Carbonylating Reagents

Jiang Nan, Pu Chen, Xue Gong, Yan Wei Hu et autres

A novel metal-free C-H [5 + 1] carbonylative annulation of 2-alkenyl/pyrrolylanilines with dioxazolones has been established for the assembly of the privileged quinolinones and pyrrolyl-fused quinoxalinones. Entirely differing from the existing reports, the dioxazolones herein behave with an innovative chemistry and first …

Non‐stereoselective C(sp 2 )– H Activation Followed by Selective Functionalization of Metallacyclic Intermediate

Xue Gong, Bo Wang, Guoyong Song

Catalytic stereoselective functionalization of C(sp2)H bonds represents a highly atom- and step-economical paradigm toward the construction of an incredibly diverse array of chiral organic compounds. Such processes constitute a significant challenge involving controlling both the chemo- and stereoselectivity. In this chapter, we …
