Abstrakt: A series of 4-arylimidazolones have been accessed via late-stage, palladium-mediated arylation of acetone- and cyclohexanone-derived 4-chloroimidazolones. The 4-chloroimidazolones were prepared via a novel rearrangement of the corresponding imidazolone N-oxides. This communication serves as an expansion of chemistry originally developed for our glucagon receptor antagonist program.
