Wang, Guanghui published the artcileDouble N,B-Type Bidentate Boryl Ligands Enabling a Highly Active Iridium Catalyst for C-H Borylation, Computed Properties of 929626-16-4, the publication is Journal of the American Chemical Society (2015), 137(25), 8058-8061, database is CAplus and MEDLINE.

Boryl ligands hold promise in catalysis due to their very high electron-donating property. In this communication double N,B-type boryl anions were designed as bidentate ligands to promote an sp² C-H borylation reaction. A sym. pyridine-containing tetraaminodiborane(4) compound was readily prepared as the ligand precursor that could be used, in combination with [Ir(OMe)(COD)]₂, to in situ generate a highly active catalyst for a broad range of (hetero)arene substrates including highly electron-rich and/or sterically hindered ones. This work provides the 1st example of a bidentate boryl ligand in supporting homogeneous organometallic catalysis.

Zhang, Mingjuan published the artcileCopper immobilized on biomimetic assembled calcium carbonate/carboxymethylcellulose hybrid: a highly active recoverable catalyst for CuAAC reactions, Formula: C7H6Cl2, the publication is Research on Chemical Intermediates (2021), 47(9), 3883-3898, database is CAplus.

A novel copper immobilized on biomimetic assembled CM-cellulose/calcium carbonate hybrid (Cu^II@CMC/CaCO₃) as an efficient heterogeneous catalyst for the synthesis of 1,2,3-triazoles has been described herein. The fabrication of Cu^II@CMC/CaCO₃ is accomplished through a bioinspired mineralization process using sodium CM-cellulose (CMC-Na) as the template and ion exchange agent, while the metathesis, nucleation, assemble, hybridization, and immobilization of Cu(II) occurred by successful treatment with CaCl₂, Na₂CO₃, and CuSO₄ in water at room temperature The resultant Cu^II@CMC/CaCO₃ hybrid was well characterized by various analyses such as FT-IR, XRD, SEM, EDX, EDX-mapping, TEM, and TGA techniques. In the presence of low copper loading of Cu^II@CMC/CaCO₃ hybrid, benzylic halides, azide, and alkynes proceeded smoothly to afford 1,4-disubstituted 1,2,3-triazoles in high yields. The catalyst can be conveniently recovered from the reaction mixture by filter and reused for at least 5 consecutive runs with a slight drop in its catalytic activity. The remarkable activity and stability of the catalyst may be attributed to the coordination of both carboxyl and hydroxyl groups of the hybrid of CMC/CaCO₃.

Xu, Zhian published the artcileCuSO₄ nanoparticles loaded on carboxymethylcelulose/polyaniline composites: A highly efficient catalyst with enhanced catalytic activity in the synthesis of propargylamines, benzofurans, and 1,2,3-triazoles, Recommanded Product: 3-Chlorobenzylchloride, the publication is Applied Organometallic Chemistry (2021), 35(10), e6349, database is CAplus.

A novel and efficient heterogeneous CuSO₄ nanoparticles (CuSO₄ NPs) immobilized on CM-cellulose/polyaniline (CuSO₄NPs@CMC/PANI) composites were prepared via one-pot and one-step interfacial oxidative polymerization of aniline with sodium CM-cellulose (CMC) as soft template and CuSO₄ as catalyst. The in situ formed CuSO₄ NPs were dispersed uniformly and firmly on the resultant composites and stabilized by complexation with hydroxyl groups (OH), carboxylate groups (COO^–), nitrogen atoms, and delocalized π-π conjugate benzenoid and quinoid moieties of CMC/PANI composites. The morphol., composition, and structure of the as-fabricated composites were systematically characterized by XPS, transmission electron microscopy (TEM), SEM (SEM), energy-dispersive X-ray spectroscopy (EDS), Fourier transform IR spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric anal. (TGA), and derivative thermogravimetry (DTG) techniques. The CuSO₄NPs@CMC/PANI composites were successfully applied as catalysts in aldehyde-alkyne-amine (A³) coupling reactions, A³-cycloisomerization tandem reactions, and Cu-catalyzed azide-alkyne cycloaddition (CuAAC) reactions. All reactions proceeded smoothly and afforded the desired products in excellent yields. Moreover, no significant decrease in catalytic ability was observed in A³ model reaction after 15 recycles, indicating CuSO₄NPs@CMC/PANI composites exhibited easy separability and high reusability. Tolerance of wide scope of substrate, excellent catalytic activity, easy operation, recycling of catalyst, and environmental benign are the salient features of these catalytic process.

Du, Daohai published the artcileStructure-Guided Development of Small-Molecule PRC2 Inhibitors Targeting EZH2-EED Interaction, Name: 1-(Chloromethyl)-4-(trifluoromethyl)benzene, the publication is Journal of Medicinal Chemistry (2021), 64(12), 8194-8207, database is CAplus and MEDLINE.

The cocrystal structure of EZH2-embryonic ectoderm development (EED) in complex with astemizole at 2.15 Å was reported. The structure elucidated the detailed binding mode of astemizole to EED and provided a structure-guided design for the discovery of a novel EZH2-EED interaction inhibitor, DC-PRC2in-01 I, with an affinity Kd of 4.56μM. DC-PRC2in-01 I destabilized the PRC2 complex, thereby leading to the degradation of PRC2 core proteins and the decrease of global H3K27me3 levels in cancer cells. The proliferation of PRC2-driven lymphomas cells was effectively inhibited, and the cell cycle was arrested in the G0/G1 phase. Together, these data demonstrated that DC-PRC2in-01 I could be an effective chem. probe for investigating the PRC2-related physiol. and pathol. and providing a promising chem. scaffold for further development.
