Application

(Ra,R,R)-SIPHOS-PE serves as a versatile chiral ligand and catalyst for an array of chemical transformations. It finds application in the preparation of tricyclic alkaloid (+)-aphanorphine through asymmetric carboamination and Friedel-Crafts reactions. Additionally, it is used in the synthesis of chiral ketones via hydroacylation of olefins with salicylaldehyde derivatives and in the enantioselective production of substituted pyrrolidine derivatives through Pd-catalyzed alkene aminoarylation reactions. The compound is also employed as a chiral ligand in copper-catalyzed asymmetric allylic alkylation with dialkylzincs, conjugate addition of diethylzinc to enones, and ring-opening of oxabicyclic alkenes using Grignard reagents. Furthermore, it plays a role in palladium-catalyzed asymmetric hydrosilylation of styrenes and asymmetric carboamination reactions. Its versatility extends to nickel-catalyzed asymmetric hydrovinylation of α-alkyl vinylarenes, iridium-catalyzed asymmetric hydrogenation of cyclic enamines and imines, as well as gold-catalyzed asymmetric [2 + 2] cycloaddition reactions. Lastly, it is involved in rhodium-catalyzed asymmetric hydroacylation of salicylaldehydes to form homoallylic sulfides.
