This chemical is primarily utilized in the field of organic synthesis, particularly as a chiral ligand or catalyst in asymmetric reactions. Its unique structure, featuring a dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin core, makes it effective in promoting enantioselective transformations, which are crucial for producing optically active compounds in pharmaceuticals and fine chemicals. Additionally, its sterically hindered and electron-rich aromatic groups enhance its ability to stabilize transition states, improving reaction efficiency and selectivity. It is often employed in metal-catalyzed processes, such as hydrogenation or cross-coupling reactions, where high enantiomeric purity is required. Its application extends to the development of novel therapeutic agents and advanced materials with specific chiral properties.
