Anthracene photodimer has a prochiral skeleton, which can be employed as the core structure to construct new chiral ligands. In previous works, the monophosphine ligands derived from optically active anthracene photodimer were prepared through resolution using high performance liquid chromatography, which became a bottleneck for the synthetic scale and cost control. Herein, an inexpensive and operationally friendly route for these ligands is reported, based on chemical resolution. The route features the use of a proline-derived chiral auxiliary that facilitate successful chemical resolution of 1-amino substituted anthracene photodimer. From the resulting optically pure enantiomers, divergent syntheses of a series of anthracene photodimer-derived monophosphine ligands have been achieved. Prepared from the above route, the chiral monophosphine ligand (Sa,Sp)-L1 has been applied to palladium-catalyzed asymmetric allylic amination reactions, which is suitable for a wide range of aniline-type nucleophiles with high yield and enantioselectivity.
