Description

Bicyclo[3.3.1]Nonane-2,6-Diol, 3,3,7,7-Tetramethyl-, (1R,2R,5R,6R)- (9Ci) is a high-purity, stereochemically defined bicyclic diol building block, valued for its rigid, three-dimensional scaffold. This compound is essential for advanced organic synthesis, particularly in the development of chiral ligands, complex natural product analogs, and sophisticated pharmaceutical intermediates. It is primarily sought by R&D chemists and process development teams in the pharmaceutical, agrochemical, and specialty chemical industries seeking to impart specific stereochemistry and conformational rigidity into their target molecules. CAS No. 639858-20-1.

Application

• Chiral Ligand Synthesis: Serves as a core scaffold for constructing novel, sterically hindered ligands used in asymmetric catalysis.
• Pharmaceutical Intermediates: A key building block in the synthesis of complex active pharmaceutical ingredients (APIs) requiring defined stereocenters and a rigid backbone.
• Natural Product & Terpene Analog Synthesis: Used to mimic the complex polycyclic structures found in natural products for drug discovery and fragrance development.
• Advanced Material Monomers: Employed in the research of high-performance polymers and resins where the bicyclic structure enhances thermal stability and mechanical properties.
• Agrochemical Active Ingredients: Utilized in the design of novel herbicides, fungicides, or insecticides with specific three-dimensional activity.
• Supramolecular Chemistry: Acts as a conformationally locked spacer or connector unit in the design of host-guest systems and molecular machines.
