Application

Atropisomeric MeOBIPHEP ligands

(R)-(6,6′-Dimethoxybiphenyl-2,2′-diyl)bis[bis(3,5-di-tert-butylphenyl)phosphine] can be used as a ligand to prepare:

• 1,2-Dihydropyridines through Rh-catalyzed cycloaddition of diynes to sulfonimines.
• Enantiorich disubstituted γ-lactams via intramolecular allylic alkylation reaction using Pd catalyst.
• A Ru-metal complex, which acts as a hydrogenation catalyst applicable in the synthesis of an organic building block (S)-3-fluoromethyl-γ-butyrolactone.

Conditionnement
