The development of novel chiral phosphine ligands is a key area of research in organic synthesis. In this study, we report an efficient synthetic method for the preparation of helically chiral monophosphorus ligands. 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.
