3Application of Langlois' reagent(NaSO_(2)CF_(3)) in C–H functionalisation显示文摘The process of selectively introducing a CF_(3) group into an organic molecule using inexpensive, stable, and solid sodium trifluoromethanesulfinate has rapidly advanced in recent years to become an eco-friendly method used by organic chemists to synthesize various natural and bioactive molecules. This review focuses on advances made within the last five years regarding C-H functionalisation, namely thermochemical C(sp^(2))-H (thio)trifluoromethylations, photochemical C(sp^(2))-H trifluoromethylations, and electrochemical C(sp^(2))-H trifluoromethylations, using Langlois’ reagent (NaSO_(2)CF_(3)).Jiabin Shen Jun Xu Lei He Chenfeng Liang Wanmei Li 2022Chinese Chemical Letters2022,33,3:1

5Molecular oxygen-mediated selective hydroxyalkylation and alkylation of quinoxalin-2(1H)-ones with alkylboronic acids显示文摘Herein, an efficient molecular oxygen-mediated method for the selective hydroxyalkylation and alkylation of quinoxalin-2(1 H)-ones with alkylboronic acids under transition-metal free conditions has been developed. This strategy demonstrates a broad scope of quinoxalin-2(1 H)-ones and alkylboronic acids, giving3-hydroxyalkylquinoxalin-2(1 H)-ones and 3-alkylquinoxalin-2(1 H)-ones in moderate-to-good yield. Control experiments reveal that a radical pathway is involved.Hongdou Zhang Jun Xu Yani Ouyang Xiaoguang Yue Chenxin Zhou Zhigang Ni Wanmei Li 2022Chinese Chemical Letters2022,33,4:0
6On the Fourth Power Mean of Generalized Three-Term Exponential Sums显示文摘The computational problem of fourth power mean of generalized three-term exponential sums is studied by using the trigonometric identity and the properties of the reduced residue system. Some explicit formulas for the fourth power mean of generalized three-term exponential sums under different conditions are given.Huaning LIU Wanmei LI 2017Journal of Mathematical Research with Applications2017,37,2:0
7Predatory bacterial hydrogels for topical treatment of infected wounds显示文摘Wound infection is becoming a considerable healthcare crisis due to the abuse of antibiotics and the substantial production of multidrug-resistant bacteria.Seawater immersion wounds usually become a mortal trouble because of the infection of Vibrio vulnificus.Bdellovibrio bacteriovorus,one kind of natural predatory bacteria,is recognized as a promising biological therapy against intractable bacteria.Here,we prepared a B.bacteriovorus-loaded polyvinyl alcohol/alginate hydrogel for the topical treatment of the seawater immersion wounds infected by V.vulnificus.The B.bacteriovorus-loaded hydrogel(BG)owned highly microporous structures with the mean pore size of 90μm,improving the rapid release of B.bacteriovorus from BG when contacting the aqueous surroundings.BG showed high biosafety with no L929 cell toxicity or hemolysis.More importantly,BG exhibited excellent in vitro anti-V.vulnificus effect.The highly effective infected wound treatment effect of BG was evaluated on mouse models,revealing significant reduction of local V.vulnificus,accelerated wound contraction,and alleviated inflammation.Besides the high bacterial inhibition of BG,BG remarkably reduced inflammatory response,promoted collagen deposition,neovascularization and re-epithelization,contributing to wound healing.BG is a promising topical biological formulation against infected wounds.Yan Liu Bo Zhuang Bochuan Yuan Hui Zhang Jingfei Li Wanmei Wang Ruiteng Li Lina Du Pingtian Ding Yiguang Jin 2023Acta Pharmaceutica Sinica B2023,13,1:0
8Rapid alkenylation of quinoxalin-2(1H)-ones enabled by the sequential Mannich-type reaction and solar photocatalysis显示文摘Herein,a rapid alkenylation of quinoxalin-2(1H)-ones enabled by a combination of Mannich-type reaction and solar photocatalysis is demonstrated.A wide range of functional groups are compatible,affording the corresponding products in moderate-to-good yields.Control experiments illustrate that the in situ generated^(1)O_(2)plays a central role in this reaction.This green and efficient strategy provides a practical solution for the synthesis of potentially bioactive compounds that containing a 3,4-dihydroquinoxalin-2(1H)-one structure.Lin Huang Jun Xu Lei He Chenfeng Liang Yani Ouyang Yongping Yu Wanmei Li Pengfei Zhang 2021Chinese Chemical Letters2021,32,11:0
