Diverse trifluoromethyl-substituted compounds were synthesized by deoxofluorination of cinnamic and (hetero)aromatic carboxylic acids with sulfur tetrafluoride. The obtained products were used as starting materials in the preparation of novel fluorinated amino acids, anilines, and aliphatic amines - valuable building blocks for medicinal chemistry and agrochemistry.

Selective anti-markovnikov cyclization and hydrofluorination reaction in superacid HF/SbF5: A tool in the design of nitrogen-containing (fluorinated) polycyclic systems
Compain, Guillaume,Bonneau, Celine,Martin-Mingot, Agnes,Thibaudeau, Sebastien
, p. 4463 - 4472 (2013/06/05)
The selective synthesis of tetrahydroquinolines and fluorinated arylamines was performed in superacid HF/SbF5 through a superelectrophilic ammonium-carbenium activation process. This anti-Markovnikov oriented reaction was applied to the straightforward synthesis of highly valued (fluorinated) nitrogen-containing heterocyclic compounds.

supporting information; experimental part, p. 5877 - 5879 (2012/08/14)
Anti-Markovnikov additions to non-conjugated unsaturated amines in superacid are reported. In situ NMR studies, DFT calculations and labelled substrates reactions support the involvement of new ammonium-carbenium superelectrophiles in this original proces

We have previously reported on antitussive effect of (5R,9R,13S,14S)-17-cyclopropylmethyl-6,7-didehydro-4,5-epoxy-5′,6′-dihydro-3-methoxy-4′H-pyrrolo[3,2,1-ij]quinolino[2′,1′:6,7]morphinan-14-ol(1b) methanesulfonate (TRK-850), a selective δ opioid receptor antagonist which markedly reduced the number of coughs in a rat cough model. We designed TRK-850 based on naltrindole (NTI), a typical δ opioid receptor antagonist, to improve its permeability through the blood-brain barrier by introducing hydrophobic moieties to NTI. The ED50 values of NTI and compound 1b by intraperitoneal injections were 104 μg/kg and 2.07 μg/kg, respectively. This increased antitussive potency probably resulted from the improved brain exposure of compound 1b. However, 1b was extremely unstable toward metabolism by cytochrome P450. In this study, we designed and synthesized compound 1b derivatives to improve the metabolic instability, which resulted in affording highly potent and metabolically stable oral antitussive agent (5R,9R,13S,14S)-17-cyclopropylmethyl-6,7-didehydro-4,5-epoxy-8′-fluoro-5′,6′-dihydro-4′H-pyrrolo[3,2,1-ij]quinolino[2′,1′:6,7]morphinan-3,14-diol (1c) methanesulfonate (TRK-851).
Selectivity in the Hydrogenation of 6- and 8-Substituted-quinolines

, p. 1933 - 1939 (2007/10/02)
Quinoline (1) and the 6- or 8-substituted-quinolines (2)-(14) (R = Me, Pri, But, Ph, OMe, OH, CF3, or F) were hydrogenated catalytically on platinum under either weakly basic (solvent MeOH) or strongly acidic (solvent CF3CO2H) conditions.In methanol the only product was the corresponding 1,2,3,4-tetrahydro-compound.In trifluoroacetic acid, compounds hydrogenated in the benzene ring were isolated as major products; both electron-withdrawing and electron-donating substituents at C-6 or C-8 cause (sometimes drastic) reduction in yield.The products were characterized by their 1H and 13C n.m.r. spectra.
