Description

Ethanone, 1-[(1R,5S)-6,6-Dimethylbicyclo[3.1.1]Hept-2-En-2-Yl]- (9Ci) is a high-purity, optically active ketone derivative of pinene, offering a unique chiral scaffold for advanced synthesis. This compound matters as a critical chiral building block and intermediate for the development of pharmaceuticals, agrochemicals, and specialty fragrances, where stereochemical control is paramount. It is needed by R&D chemists and process development scientists in the pharmaceutical, flavor & fragrance, and fine chemical industries seeking to introduce complex, terpene-based stereocenters into their target molecules.

Application

• Pharmaceutical Intermediate: Serves as a key chiral precursor for the synthesis of active pharmaceutical ingredients (APIs), particularly in therapeutic areas requiring terpenoid or rigid bicyclic structures.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, where its specific stereochemistry can influence biological activity.
• Flavor and Fragrance Ingredient: Acts as a starting material for creating novel, high-value aroma chemicals with woody, pine-like olfactory characteristics.
• Asymmetric Catalysis Ligand Synthesis: Provides a backbone for developing novel chiral ligands and organocatalysts used in enantioselective transformations.
• Material Science Research: Investigated as a monomer or functional additive for creating polymers with specific optical or structural properties.
• Academic & Industrial R&D: A valuable tool for methodological studies in organic synthesis and natural product analog development.
