Description

Ethanone, 1-(1R,2R,4R)-Bicyclo[2.2.1]Hept-5-En-2-Yl- (9Ci) is a high-purity, chiral bicyclic ketone derivative of significant interest in advanced organic synthesis. This compound matters as a versatile and stereochemically defined building block for constructing complex molecular architectures with precise three-dimensional control. It is primarily needed by research and development chemists in the pharmaceutical and agrochemical industries for applications such as asymmetric synthesis, chiral ligand development, and the preparation of novel active ingredients.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of novel active pharmaceutical ingredients (APIs), particularly in areas requiring rigid, bicyclic frameworks.
• Asymmetric Catalysis: Serves as a precursor for the synthesis of chiral ligands and organocatalysts used in enantioselective transformations.
• Agrochemical Synthesis: Used in the development of new herbicides, fungicides, and insecticides where its specific stereochemistry can influence biological activity.
• Material Science Research: Employed as a monomer or cross-linking agent in the development of specialty polymers with unique thermal or mechanical properties.
• Fragrance & Flavor Chemistry: Acts as an intermediate for synthesizing high-value aroma chemicals with complex, woody, or camphoraceous notes.
• Academic & Process Chemistry: A valuable tool in methodological studies for ring-opening, Diels-Alder, and other cycloaddition reactions due to its strained norbornene core.
