Description

R-5,5',6,6',7,7',8,8'-Octahydro-3,3'-Diphenyl-[1,1'-Binaphthalene]-2,2'-Diol is a sophisticated chiral ligand and building block of significant interest in advanced organic synthesis. Its value lies in its rigid, three-dimensional structure, which is highly effective for inducing enantioselectivity in catalytic reactions. This compound is essential for researchers and manufacturers in the pharmaceutical and fine chemical industries who require high-purity chiral auxiliaries for asymmetric synthesis and catalyst development.

Application

• As a chiral ligand in asymmetric metal-catalyzed reactions, including hydrogenation, Diels-Alder, and aldol additions.
• As a key building block for the synthesis of more complex, functionalized BINOL (1,1'-Bi-2-naphthol) derivatives.
• In the research and development of novel organocatalysts for enantioselective transformations.
• For the preparation of chiral molecular recognition systems and sensors.
• In the synthesis of advanced pharmaceutical intermediates where precise stereochemical control is critical.
• As a precursor for chiral polymers and materials with specific optical properties.
