Nitrogen heterocycles by palladium-catalyzed cyclization of amino-tethered vinyl halides and ketone enolates

The scope and limitations of Pd(0)-catalyzed intramolecular coupling of amino-tethered vinyl halides and ketone enolates as a methodology for the synthesis of nitrogen heterocycles have been studied. This reaction constitutes a synthetic procedure to obtain bridged, condensed, and monocyclic nitrogen-containing compounds.
