A catalyst composed of 10 mol% of Pd(OAc)(2) and (R,R)-PhBox was proven to be effective in the asymmetric haloiminolactonization of alpha-allylmalon-amides with N-halosuccinimides, giving the dihalogenated cyclic products with good diastereomeric ratio (up to 89/11) and enantiomeric excess (up to 72% ee).
