supporting information; experimental part, p. 1847 - 1852 (2011/07/31)
A highly enantioselective organocatalytic conjugate addition of acetylacetone to 3-ylideneoxindoles is described. This method provides polysubstituted oxindoles in good to excellent enantioselectivities and high isolated yields. Georg Thieme Verlag Stuttg
