Palladium-Catalyzed Enantioselective Synthesis of P(V)-Stereogenic Compounds via Desymmetric Annulation of Prochiral Phosphinamides and Aryl Iodides

The enantioselective synthesis of P(V)-stereogenic compounds has emerged as an interesting research topic primarily due to their significant biological activity and broad application prospects. Herein, we disclose a method for the construction of P(V)-stereogenic compounds from prochiral phosphinamides and aryl iodides via palladium- and chiral norbornene-catalyzed desymmetric annulation. The P(V)-stereogenic compounds were formed with a broad scope with excellent enantiomeric excesses. It is noteworthy that the synthetic value of this procedure was proven by a variety of transition metal-catalyzed cross-coupling reactions using the C-Br bond on the product as a versatile linchpin electrophile.
