Stereoselective homocoupling of chiral 1-aroylacetyl-2-imidazolidinones by oxidation with Br2

The oxidative coupling of sodium enolates of (4R,5S)-1-aroylacetyl-3,4-dimethyl-5-phenyl-2-imidazolidinones with Br2 as the oxidant affords the R,R-dimers stereoselectively. The R,R-selectivity can be explained by a radical coupling mechanism.
