Pd-Catalyzed Asymmetric Allylic Etherification Using Chiral Biphenol-Based Diphosphinite Ligands and Its Application for The Formal Total Synthesis of (−)-Galanthamine

A library of novel chiral biphenol-based diphosphinite (BOP) ligands was designed and created. These BOP ligands were applied to a Pd-catalyzed intermolecular allylic etherification reaction, which provided a key intermediate for the formal total synthesis of (−)-galanthamine with 97% ee in 97% yiel...

Zusammenfassung:A library of novel chiral biphenol-based diphosphinite (BOP) ligands was designed and created. These BOP ligands were applied to a Pd-catalyzed intermolecular allylic etherification reaction, which provided a key intermediate for the formal total synthesis of (−)-galanthamine with 97% ee in 97% yield.
