Description

Bicyclo[2.2.1]Hept-5-Ene-2-Carboxaldehyde, 2-Ethyl-, (1S,2S,4S)- (9Ci) is a high-purity, chiral bicyclic aldehyde building block of significant interest in advanced organic synthesis. Its rigid, functionalized norbornene-like structure makes it a valuable precursor for constructing complex, three-dimensional molecular architectures. This compound is primarily sought after by research and development chemists in the pharmaceutical and agrochemical industries for applications in asymmetric synthesis, chiral ligand development, and the creation of novel active ingredients.

Application

• Chiral Intermediate in Pharmaceutical Synthesis: Serves as a key starting material or advanced intermediate for the production of enantiomerically pure drug candidates, particularly those requiring complex, polycyclic frameworks.
• Agrochemical Active Ingredient Development: Used in the research and synthesis of novel herbicides, fungicides, and insecticides where its specific stereochemistry can influence biological activity.
• Asymmetric Catalyst and Ligand Synthesis: Employed in the design and preparation of new chiral ligands and organocatalysts for stereoselective transformations.
• Material Science Research: Acts as a monomer or cross-linking agent in the development of specialized polymers with unique thermal or mechanical properties derived from the norbornene core.
• Fine Chemical and Flavor/Fragrance Synthesis: Utilized in the multi-step synthesis of complex natural product analogs and high-value aroma chemicals.
