Description

Bicyclo[2.2.1]Hept-5-Ene-2,3-Dimethanol, -α--Ethenyl--α--Methyl-, (-α-S,1S,2R,3S,4R)- (9Ci) is a high-purity, stereochemically defined chiral building block of significant interest in advanced organic synthesis. Its complex, rigid bicyclic structure with multiple functional handles makes it a valuable precursor for constructing sophisticated molecular architectures. This compound is primarily sought after by research and development teams in the pharmaceutical and fine chemical industries for applications in asymmetric catalysis and the synthesis of novel active pharmaceutical ingredients (APIs).

Application

• Chiral Ligand Synthesis: Serves as a key intermediate for the development of novel, sterically demanding ligands used in asymmetric catalysis.
• Pharmaceutical Intermediates: Used in the research and development of complex, stereospecific drug candidates, particularly in central nervous system (CNS) and antiviral therapeutic areas.
• Advanced Material Monomers: Acts as a specialized monomer for creating polymers with unique thermal and mechanical properties due to its rigid norbornene core.
• Fine Chemical Synthesis: Employed in multi-step synthetic routes to build complex natural product analogs and other high-value specialty chemicals.
• Academic & Industrial R&D: A critical tool for methodological development in organic chemistry, enabling studies on stereoselective transformations and reaction mechanisms.
