Selective Anti-Markovnikov Cyclization and Hydrofluorination Reaction in Superacid HF/SbF5: A Tool in the Design of Nitrogen-Containing (Fluorinated) Polycyclic Systems
摘要:
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.

Aromatic compounds bearing a basic nitrogen atom can be converted to the corresponding nitricacid salts. Mono-nitration of the compounds can be carried out by adding a dichloromethane solution of the salts to sulfuric acid, or by adding acetyl chloride (or trifluoroacetic anhydride) to a dichloromethane solution of the salts. This protocol provides, among other benefits, the most convenient and reliable
