Description

Bicyclo[2.2.1]Hept-5-Ene-2-Carboxaldehyde, 3-Ethenyl-, (1R,2S,3R,4S)-Rel- (9Ci) is a high-value, stereochemically defined chiral building block essential for advanced organic synthesis. This compound matters because its rigid norbornene core and strategically positioned aldehyde and vinyl groups enable the construction of complex, three-dimensional molecular architectures with high precision. It is critically needed by research and development chemists in the pharmaceutical and agrochemical industries for creating novel active ingredients, as well as by material scientists developing specialty polymers and functionalized ligands.

Application

• Pharmaceutical Intermediate: Serves as a key chiral precursor in the synthesis of novel drug candidates, particularly for central nervous system (CNS) and antiviral therapies.
• Agrochemical Synthesis: Used to construct complex, bioactive molecules for next-generation herbicides, fungicides, and insecticides with enhanced selectivity.
• Material Science: Acts as a functional monomer for ring-opening metathesis polymerization (ROMP) to create specialty polymers with unique thermal and mechanical properties.
• Catalyst & Ligand Development: Employed in the design and synthesis of novel chiral ligands and organocatalysts for asymmetric synthesis.
• Fine Chemical Production: A versatile starting material for synthesizing complex natural product analogs and other high-value fine chemicals.
• Academic & Industrial R&D: A critical reagent for methodological development in organic chemistry and exploration of new chemical spaces.
