Pd-Catalyzed Dehydrogenative Cross-Coupling of Polyfluoroarenes with Heteroatom-Substituted Enones
摘要:
The first example of intermolecular regioselective alpha-arylation of heteroatom-substituted enones with polyfluoroarenes via twofold C-H bond functionalization using a palladium catalyst is reported. This approach provides rapid access to a wide range of alpha-fluoroarylated enones of interest in life science.

Electron deficient 3-quinolinecarboxylic acids undergo ready decarboxylation in the presence of cyanide ion. This reaction most likely requires the addition of CN− to the 2-position of the quinoline (or naphthyridine) nucleus to provide a β-keto acid intermediate that rapidly decarboxylates to give the 3-H substituted product.
The first example of intermolecular regioselective alpha-arylation of heteroatom-substituted enones with polyfluoroarenes via twofold C-H bond functionalization using a palladium catalyst is reported. This approach provides rapid access to a wide range of alpha-fluoroarylated enones of interest in life science.
