Description

(1S)-2,2'-Bis(Methoxymethoxy)-[1,1'-Binaphthalene]-3,3'-Diol is a high-purity, enantiomerically pure chiral ligand and synthetic intermediate of significant importance in asymmetric catalysis. This compound matters because it provides a crucial scaffold for constructing highly selective catalysts used in the synthesis of complex, single-enantiomer molecules. It is primarily needed by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs) and fine chemicals where stereochemical control is paramount.

Application

• As a chiral ligand in asymmetric metal-catalyzed reactions, including hydrogenation, coupling, and addition reactions.
• As a key synthetic intermediate for the preparation of more complex BINOL (1,1'-Bi-2-naphthol) and BINAP derivatives.
• In the research and development of novel organocatalysts for enantioselective synthesis.
• For the asymmetric synthesis of pharmaceuticals, agrochemicals, and specialty materials requiring high optical purity.
• As a building block in supramolecular chemistry and for the creation of chiral molecular devices and sensors.
• In academic and industrial R&D focused on exploring new methodologies in stereoselective catalysis.
