We next explored the possibility of transforming the Rh-catalyzed asymmetric allylic arylation into an iterative process to generate 1,2-polyaryl chains with precise enantio-and diastereocontrol (Figure ). Developing such a stereoselective method would not only set a definitive benchmark for ligand-controlled diastereoselective synthesis but also address a longstanding challenge in organic synthesis, as, to the best of our knowledge, no stereoselective iterative methods for synthesizing contiguous aryl-substituted stereogenic centres have been established.
