The development of novel chiral phosphine ligands is a key area of research in organic synthesis. An efficient synthetic method for the preparation of helically chiral monophosphorus ligands was reported. Using this approach, four structurally distinct, helically chiral, bowl-shaped monophosphorus ligands were successfully synthesized. Their catalytic activities were systematically evaluated in palladium-catalyzed C—C and C—N bond-forming reactions. Enantiopure ligands were obtained via HPLC resolution. Although these reactions did not achieve high enantiocontrol, the ligands demonstrated a unique helical chiral cavity and excellent catalytic activity. These findings suggest that this class of compounds warrants further exploration in other asymmetric catalytic reactions.
Key words: phosphorus ligand; helically chiral; bowl shape; catalysis
