Description

S-3,3'-Bis((2-Naphthyl)-5,5',6,6',7,7',8,8'-Octahydro-1,1'-Bi-2,2'-Naphthol is a sophisticated chiral ligand and building block of significant importance in asymmetric synthesis. Its value lies in its ability to induce high enantioselectivity in catalytic reactions, which is critical for producing single-enantiomer compounds. This product is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries who require precise stereochemical control.

Application

• As a chiral ligand for transition metal catalysts in asymmetric hydrogenation and carbon-carbon bond-forming reactions.
• As a key intermediate in the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs).
• In the development of novel catalysts for the production of agrochemicals and flavors & fragrances.
• As a resolving agent or chiral auxiliary in stereoselective organic synthesis.
• For research and development in academic and industrial laboratories focused on asymmetric catalysis.
• In the preparation of advanced materials where chiral induction is required.
