Description

S-3,3'-Di-9-Phenanthrenyl-5,5',6,6',7,7',8,8'-Octahydro-1,1'-Binaphthalene]-2,2'-Diol is a sophisticated, chiral binaphthol derivative with a complex, sterically hindered structure, making it a valuable ligand and building block in advanced organic synthesis. Its significance lies in its ability to induce high enantioselectivity in catalytic asymmetric reactions, which is critical for producing single-enantiomer compounds. This product is essential for research and development chemists in the pharmaceutical, agrochemical, and specialty chemical industries who require precise chiral control for creating novel active ingredients and functional materials.

Application

• As a chiral ligand in asymmetric metal catalysis (e.g., hydrogenation, C-C bond formation).
• As a key building block for constructing complex molecular architectures in total synthesis.
• In the development of enantioselective organocatalysts for green chemistry applications.
• For research into novel chiral stationary phases (CSPs) for analytical and preparative chromatography.
• In the synthesis of functional materials with specific optical or electronic properties.
• As a pharmaceutical intermediate in the production of enantiomerically pure drugs.
