A new type of axially chiral phosphine-alkene ligands have been developed for Pd-catalyzed asymmetric allylic alkylation of indoles via a two-step modular synthesis. The reaction provides a series of chiral allylindole products with generally high yields (up to 95%) and excellent enantioselectivities (up to 96% ee).
