Significance
Structures possessing a 3-arylpiperidine and similar heterocyclic scaffolds are known to display a broad spectrum of biological activity. Cyclic enaminones are useful precursors for that type of compounds. This method of a enaminone arylation competes favorably with the previously known halogenation-cross-coupling sequence, as it proceeds in a single step. A variety of enaminones and aryltrifluoroborates can be successfully involved in this reaction. Many functional groups including halides are tolerated.
