Spiroketal backbone based diphosphine ligands (SKP) were disclosed to be highly efficient and enantioselective (94 ->.99% ee) in the palladium catalyzed asymmetric allylic amination of 2-diethylphosphonate- substituted allylic acetates, affording a series of chiral beta- aminophosphonates bearing an alpha- methylene functionality in high yields with excellent regioselectivities.
