Highly effective chiral phosphorus amidite-olefin ligands for palladium-catalyzed asymmetric allylic substitutions

摘要

This paper describes the development of a type of novel P- olefin hybrid ligand by the incorporation of terminal olefins onto phosphorus amidite ligands for palladium-catalyzed asymmetric allylic alkylations of indoles and substitutions with amines to give the desired products in 70-97% yield with 91-98% ee.
