Electrolyte engineering via ether solvent fluorination for developing stable non-aqueous lithium metal batteries
Fluorination of solvents, useful for non-aqueous lithium-based batteries, improves the electrochemical stability but decreases the ionic conductivity. Here, the authors report a targeted functionalization of an ether solvent to balance the electrolyte ioni ...
NATURE PORTFOLIO2023Synthesis and Applications of Ynimines and Enantioselective Total Synthesis of Artatrovirenol A
The first chapter of this thesis describe the development of a general synthesis of ynimines, an under-exploited motif in organic chemistry. In the presence of an inexpensive copper catalyst and 2,2'-biquinoline, reaction of easily accessible O-acyloximes ...
EPFL2023Terminal Alkynes as One-Carbon Donors in [5+1] Heteroannulation: Synthesis of Pyridines via Ynimine Intermediates and Application in the Total Synthesis of Anibamine B
Qian Wang, Jieping Zhu, Rémi Hugo Lavernhe
Transition-metal-catalyzed [4+2] heteroannulation of alpha,beta-unsaturated oximes and their derivatives with alkynes has been developed into a powerful strategy for the synthesis of pyridines. It nevertheless lacks regioselectivity when unsymmetrically su ...
WILEY-V C H VERLAG GMBH2023Methanol production from CO(2)via an integrated, formamide-assisted approach
Paul Joseph Dyson, Andreas Züttel, Jorge Gustavo Uranga, Aswin Gopakumar, Gabriela Gastelu, Tim Pfister, Gunay Imanzade
The synthesis of fuels from CO2 has made tremendous progress in recent years, although practical applications remain limited. Herein, we describe a cyclic process that produces MeOH from CO(2)via formamide intermediates, which are initially reduced using N ...
ROYAL SOC CHEMISTRY2020Indole Alkaloids, Macrocycles and Heterocycles
An enantioselective total synthesis of (-)-terengganensine A, a heptacyclic monoterpene indole alkaloid, was performed. A short sequence allowed to obtain the enantio-enriched target in good overall yield. The synthesis featured a key asymmetric transfer h ...
EPFL2018α-Oxo-Ketenimines from Isocyanides and α-Haloketones: Synthesis and Divergent Reactivity
Qian Wang, Jieping Zhu, Mathias Mamboury
The palladium-catalyzed reaction of a-haloketones with isocyanides afforded -oxo-ketenimines through alpha-hydride elimination of the beta-oxo-imidoyl palladium intermediates. Reaction of these relatively stable alpha-oxo ketenimines with nucleophiles suc ...
Wiley-Blackwell2017Synthesis of Vinyl Isocyanides and Development of a Convertible Isonitrile
Qian Wang, Jieping Zhu, Martina Spallarossa
The reaction of isocyanomethylenetriphenylphosphorane, generated in situ from the corresponding phosphonium salt, with a diverse set of aldehydes afforded vinyl isocyanides in good to high yields. Excellent E-selectivity was observed for aliphatic aldehyde ...
American Chemical Society2016Designing interactions across interfaces in ionic liquids
Ionic liquids (ILs) have attracted much attention because of their unusual charac- teristics (vapor pressure, condictivity, etc.). Furthermore, they can be designed to display desired properties specific to an application (task-specific ionic liquid, TSILs ...
EPFL2016Tuning the Reactivity of Isocyano Group: Synthesis of Imidazoles and Imidazoliums from Propargylamines and Isonitriles in the Presence of Multiple Catalysts
Qian Wang, Jieping Zhu, Shuo Tong
The reaction of propargyl amines with tert-butylisonitrile in the presence of a catalytic amount of both Yb(OTf)3 and AgOTf afforded imidazoles, whereas the same reaction with primary and secondary alkylisonitriles, as well as arylisonitriles, in the prese ...
Wiley-Blackwell2015Three-Component Povarov Reaction–Heteroannulation with Arynes: Synthesis of 5,6-Dihydroindolo[1,2‑a]quinolines
Qian Wang, Jieping Zhu, Ala Bunescu
A reaction of 2-acyl substituted tetrahydroquinolines, prepared by Lewis acid-catalyzed three-component reaction of α-oxo aldehydes, anilines, and dienophiles, with in situ generated arynes afforded 5,6-dihydroindolo[1,2-a]- quinolines in good to excellent ...
