Abstract: Ethyl α-nitro-β-trifluoromethyl acrylate was synthesized by nucleophile-catalyzed reaction of ethyl nitroacetate with excess trifluoroacetaldehyde methyl hemiacetal and subsequent dehydration of the intermediate alcohol with P2O5. The synthesized nitro olefin regioselectively reacts with the substituted indoles…

Abstract: Unprecedented asymmetric exo′-selective [3 + 2] cycloaddition reactions of CF3-containing isatin-derived azomethine ylides with methyleneindolinones have been disclosed. Under bifunctional organocatalysis by cinchona-derived squaramide catalysts, a series of potential biologically important trifluoromethylated 3,3′-pyrrolidinyl-dispirooxindoles were efficiently…

Abstract: Two supramolecular tetrahedral cages based on a new electron-deficient trifluoromethyl-substituted pyridylimine ligand are synthesised by sub-component self-assembly. Their structures are characterised by NMR und UV-Vis spectroscopy, high-resolution mass spectrometry and single crystal X-ray diffraction. The…
