Synthesis of Enantiomerically Enriched Imidazolidin-2-Ones via Asymmetric Pd-Catalyzed Alkene Carboamination Reactions
A catalyst composed of Pd(2)(dba)(3) and (S)-Siphos-PE is effective for the enantioselective coupling of N-allyureas with aryl bromides to afford 4-substituted imidazolidin-2-ones with up to 95% ee. Added water leads to significantly improved enantioselectivities with electron-poor aryl halide subst...
