(R)-3,5-t-Bu-MeOBIPHEP exhibits applications as a ligand, enabling the preparation of diverse chemical compounds. It facilitates the formation of 1,2-dihydropyridines through a rhodium-catalyzed cycloaddition of diynes to sulfonimines. It enables the synthesis of enantiorich disubstituted γ-lactams through an intramolecular allylic alkylation reaction using a palladium catalyst. Additionally, (R)-3,5-t-Bu-MeOBIPHEP participates in the creation of a ruthenium-metal complex, serving as a hydrogenation catalyst for the synthesis of the organic building block (S)-3-fluoromethyl-γ-butyrolactone.
