Abstract
An efficient palladium-catalyzed asymmetric amination of 2,3-allenyl phosphates with nitrogen nucleophiles such as amines, hydroxylamines, and imides can be performed in presence of SEGPHOS or MeOBIPHEP ligand, affording the corresponding optically active 1-aminated derivatives with high enantiomeric excess.
