polysubstituted 3-acylpyrroles from readily available unsaturated ketones and N-substituted propargylated amines have been developed. An aza-Michael/alkyne carbocyclization cascade, by cooperative catalysis using pyrrolidine and a copper salt, followed by oxidation in situ gave 3-acylpyrroles, which were also transformed further to functionalized, highly substituted 3-acylpyrroles.

Vinyl halides undergo intramolecularcoupling with amino-tethered ketones, esters, and nitriles in the presence of a palladium catalyst and potassium phenoxide as the base. This reaction constitutes a useful methodology for the synthesis of monocyclic, bridged, and spirocyclic nitrogen-containing compounds.

The palladium-mediated intramolecular coupling of amino-tethered vinyl halides and ketone enolates is a useful methodology for the synthesis of nitrogen heterocycles and constitutes a new synthetic entry to the 2-azabicyclo[3.3.1]nonane framework. A study about the reaction conditions and the scope of the process is reported.
