Abstract
One-pot syntheses of 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.
