Description

1,2-Cyclohexanediamine, N1,N2-Bis(2-Pyridinylmethylene)-, [N(E),N(E),1R,2R]- CAS NO 934355-35-8 is a chiral, enantiomerically pure ligand belonging to the class of salen-type compounds. This compound matters as a highly effective and selective catalyst in asymmetric synthesis, enabling the production of chiral intermediates with high enantiomeric excess. It is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries for developing new active ingredients and advanced materials.

Application

• Asymmetric Catalysis: As a chiral ligand for transition metals (e.g., Mn, Co, Cu) in enantioselective epoxidation, cyclopropanation, and Diels-Alder reactions.
• Pharmaceutical Intermediate Synthesis: For the production of chiral active pharmaceutical ingredients (APIs) requiring high stereochemical purity.
• Agrochemical Research: In the development of enantiomerically pure herbicides, fungicides, and pesticides.
• Fine Chemical Manufacturing: For synthesizing specialty chemicals, flavors, and fragrances where chirality is critical.
• Material Science: As a building block for chiral metal-organic frameworks (MOFs) or polymeric catalysts.
• Academic & Industrial R&D: As a reference standard and reagent in methodological development for organic synthesis.
