4Recent progress in lantha-nide-catalyzed organic reactions in protic media显示文摘Lanthanide triflates are stable in water. It is possible for lanthanides to undergo many organic reactions in environmentally friendly solvents. This makes lanthanides very promising in the field of green chemistry.

Detailed mechanism study indicated that the diamine acted as a bifunctional cooperation catalyst via a bicyclic enamino-quaternary ammonium intermediate.ZHANG Long LUO SanZhong CHEN LiuJuan LI JiuYuan CHENG JinPei 2009Science China Chemistry2009,52,9:0
11Biomimetic asymmetric catalysis显示文摘Enzymes are the core for biological transformations in nature.Their structures and functions have drawn enormous attention from biologists as well as chemists since last century.The large demand of bioactive molecules and the pursuit of efficiency and greenness of synthesis have spurred the rapid development of biomimetic chemistry in the past several decades.Biomimetic asymmetric catalysis,mimicking the structures and functions of enzymes,has been recognized as one of the most promising synthetic strategies for the synthesis of valuable chiral compounds.This review summarizes the evolution of asymmetric catalysis inspired by aldolases,vitamin B_(1)/B_(6)-dependent enzymes,NAD(P)H,flavin,hydrogenases,heme oxygenases,nonheme oxygenases,and dinuclear/multinuclear metalloenzymes in aspects of biomimetic design,catalyst development and related catalytic transformations.Those well-established synthetic approaches originating from biological reactions have demonstrated the unique prowess of biomimetic asymmetric catalysis in bridging the gap between bio-catalysis and chemical synthesis.Xiao Xiao Kaini Xu Zhong-Hua Gao Zhou-Hao Zhu Changqing Ye Baoguo Zhao Sanzhong Luo Song Ye Yong-Gui Zhou Senmiao Xu Shou-Fei Zhu Hongli Bao Wei Sun Xiaoming Wang Kuiling Ding 2023Science China Chemistry2023,66,6:0

13Visible Light Promoted Direct Deuteration of Alkenes via Co(III)–H Mediated H/D Exchange显示文摘We report herein a visible light-mediated direct deuteration of alkenes with D_(2)O or deuterated methanol(MeOD)using a cobaloxime as a hydrogen/deuterium(H/D)exchange catalyst.The synergistic photoredox/Co catalysis enabled facile deuterium(D)-incorporation of a variety of terminal and internal alkenes at either terminal or benzylic positions.We proposed that this process proceeded through a sequence of reversible addition-elimination reactions and fast proton exchange involving Co(III)–H,which was generated in situ by photoreduction.Zongbin Jia Sanzhong Luo 2023CCS Chemistry2023,5,5:0
14Bio-inspired quinone catalysis显示文摘Quinoproteins are an important type of redox enzymes for biological oxidation processes. Inspired by the quinone cofactors, particularly from copper amine oxidases, a number of small molecular quinone catalysts have been developed for C-H functionalizations of amines. Bio-inspired quinone catalysts have significantly expanded the substrate scope to include branched primary amines, secondary amines and tertiary amines, far beyond the scope of quinoproteins. This review summarizes the evolution of quinone catalysts, their mechanism and catalytic applications.Ruipu Zhang Sanzhong Luo 2018Chinese Chemical Letters2018,29,8:0
15Asymmetric α-Pentadienylation of β-Ketocarbonyls and Aldehydes by Synergistic Pd/Chiral Primary Amine Catalysis显示文摘Direct alkylation with skipped enynes or cyclopropropylacetylenes represents an ideal process for the installation of pentadienyl group in terms of atom- and step-economy.The development of catalytic asymmetric versions has been frequently pursued and most of the successes have been achieved with enolizable aldehydes.We herein describe a synergistic chiral primary amine/Pd catalysis for asymmetric α-pentadienylation of β-ketocarbonyls and aldehydes with skipped enynes or cyclopropropylacetylenes.The reaction features the construction of acyclic all-carbon quaternary centers with high enantioselectivity,and good functional group tolerance and scalability.Chang You Sanzhong Luo 2023Chinese Journal of Chemistry2023,41,24:0

18Understanding how charge-charge interaction affects the stereochemistry of enamine fluorination by chiral primary amine catalysis显示文摘Electrostatic interaction, especially electrostatic attraction, usually plays critical roles in controlling the reactivity and selectivity in catalytic transformations;however, the like-charge repulsion, which is ubiquitous in physical systems, is rarely applied in reaction control. Herein we disclosed an unexpected like-charge repulsion induced enantio-control mode in primary aminecatalyzed fluorination reactions with 1-fluoro-2,4,6-trimethylpyridinium triflate. The ionic reaction works favorably in both highly polar(methanol) and non-polar(hexane) solvents, a seldom observed phenomenon in asymmetric catalysis. Erying plot analysis showed that an inversion temperature existed in Me OH, which was explained by the solvent-solute cluster model under different temperatures. Density functional theory(DFT) study and energy decomposition analysis(EDA) verified that the likecharge repulsion takes effect in polar solvent methanol, while in nonpolar solvents, the steric repulsion associated with ion-pair was found to be the major effect for the observed enantioselectivity.Yanfang Han Kai Yang Long Zhang Sanzhong Luo Jin-Pei Cheng 2023Science China Chemistry2023,66,10:0
19Catalytic Asymmetric Addition and Telomerization of Butadiene with Enamine Intermediates显示文摘Herein,we report tunable asymmetric addition and telomerization of butadiene by synergistic chiral primary amine/achiral palladium catalysis.A selection of different achiral phosphine ligand in concert with the chiral primary amine-trifluoromethanesulfonic acid(TfOH)conjugates enables both chemo-and enantioselective control of the coupling with butadiene.Bidentate[(oxydi-2,1-phenylene)-bis-(diphenylphosphine)](DPEPhos)ligand led to 1,4-addition adduct whereas monodentate(p-Tol)3P ligand gave the telomerization product.A range ofα-branchedβ-ketoesters and aldehydes could be applied to afford allylation or telomerization products bearing allcarbon quaternary centers at high efficiency and good chemo-,regio-,and stereoselectivities.Yaning Wang Jie Zhang Chang You Xueling Mi Sanzhong Luo 2022CCS Chemistry2022,4,7:0
