Palladium-Catalyzed Asymmetric Amination and Imidation of 2,3-Allenyl Phosphates
摘要:
[GRAPHICS]Asymmetric amination of 2,3-allenyl phosphates with nitrogen nucleophiles such as amines, hydroxylamines, and imides can be performed efficiently using a combination of zerovalent palladium complexes and SEGPHOS or MeOBlPHEP ligand, affording the corresponding optically active 1-aminated derivatives with enantiomeric excess of up to 97% ee.
