Cinnamoyl amide type chiral P,olefin ligands for Pd-catalyzed reactions.

We synthesized cinnamoyl amide type chiral P,olefin ligand ()-4. We successfully obtained separable diastereomers of 4d and demonstrated Pd-catalyzed asymmetric allylic substitution reactions of indoles using (,a)-4d as a chiral ligand with high enantioselectivities (up to 98% ee).
