1,4-cis-Disubstituted cyclic compounds play a pivotal role in pharmaceutical development, offering enhanced potency and bioavailability. However, their stereoselective modular synthesis remains long-standing challenge. Here, we report an innovative strategy for accessing these structures via mild conditions employing 1,3-dienes/alkyl(aryl)halides amines. This procedure exhibits wide substrate scope that tolerates various functional groups. The utility of this method is demonstrated the...
Abstract C−F insertion of carbon‐atom units is underdeveloped although it poses significant potential applications in both drug discovery and development. Herein, we report a photocatalytic protocol for late‐stage modification trifluoromethyl aromatic drugs involving formal abundant alkene feedstocks into benzylic bond selectively. This redox‐neutral transformation features mild conditions extraordinary functional group tolerance. Preliminary studies are consistent with this radical‐polar...
We report a chiral phosphoric acid-catalyzed hydrolytic parallel kinetic resolution (HPKR) of racemic epoxides and activated alcohols. Using an acyloxy-assisted activation strategy, this method enables the highly stereocontrolled hydrolysis under mild conditions. A wide range aryl-substituted secondary alcohols were effectively transformed, providing corresponding with combined yields up to 99% enantiomeric ratios exceeding 99:1.
An intriguing chiral phosphoric acid-catalyzed asymmetric hydrolytic ring-opening of racemic aziridines via regiodivergent PKR is presented, providing an efficient approach for the construction β-amino alcohols.
We unveil a novel strategy that leverages cost-effective fluorine-containing sources for rapid synthesis of fluorinated com-pounds through multicomponent reactions. Our study introduces visible light-driven palladium-catalyzed 1,4-difluoromethyl difunctionalization conjugated dienes, capitalizing on the abundant industrial resource chlorodifluoro-methane (ClCF2H, Freon-22). Illuminated by blue LED light, palladium catalyst orchestrates efficient single electron reduction Freon-22's C-Cl...
In this paper, tannic acid (TA) and Fe<sup>3+</sup> were added to form a layer of metal-polyphenol network structure on the surface nanoparticles which fabricated by zein carbon quantum dots (CQDs) encapsulating Phlorotannins (PTN). pH-responsive prepared successfully (zein-PTN-CQDs-Fe<sup>Ⅲ</sup>). Further, formation composite was confirmed series characterization methods. The zeta-potential Fourier transform infrared spectroscopy data proved that electrostatic interaction hydrogen bonding...
Cu–3Zr alloy was prepared by powder metallurgy and two-stage thermomechanical process, the microstructure evolution properties were investigated. The results show that of as-sintered is consisted coarse Cu–Zr intermetallic compounds equiaxed Cu grains. After extrusion, second phase smaller in cross section, while deformation texture matrix can be seen from longitudinal section. further drawing, grains are elongated broken into fine particles. yield strength (YS), ultimate tensile (UTS)...

Weaknesses generated in asphalt pavement structures have a serious impact on the service life of pavements. In order to improve such situations and achieve goal enhancing durability structure, this study assesses performance heavy-duty high-viscosity asphalt, using four high-performance mixtures: AC-20, SMA-13, SMA-10. Three composite were designed: 3 cm SMA-10 + SMA-10, 4 SMA-13 6 AC-20. Interlayer analysis was conducted single-layer through oblique shear tests; dynamic modulus, fatigue...
