Description

(R)-C3-Tunephos is a chiral phosphine ligand widely used in asymmetric catalysis. This compound matters for its ability to induce high enantioselectivity in critical transition metal-catalyzed reactions, enabling the production of optically pure intermediates. It is essential for R&D chemists and process engineers in the pharmaceutical, agrochemical, and fine chemical industries who require precise stereochemical control.

Application

• As a chiral ligand in asymmetric hydrogenation reactions for pharmaceutical intermediate synthesis.
• Catalyst component for enantioselective C-C and C-X bond-forming cross-coupling reactions.
• Used in the development of active pharmaceutical ingredients (APIs) requiring high optical purity.
• Key reagent in the synthesis of agrochemicals and specialty fine chemicals with defined stereochemistry.
• Research and development tool for exploring new asymmetric catalytic processes in academia and industry.
• Potential use in the synthesis of flavors, fragrances, and advanced materials.
