Description

7-Oxabicyclo[4.1.0]Hept-2-Ene-3-Carboxylicacid,5-Hydroxy-,(1S,5S,6R)-(9Ci) is a high-purity, stereochemically defined oxabicyclic compound that serves as a critical chiral building block and synthetic intermediate. Its unique fused ring structure and functional groups make it valuable for constructing complex molecular architectures with precise stereochemical control. This advanced intermediate is primarily sought after by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs) and fine chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of new therapeutic agents, particularly for complex small-molecule drugs.
• Asymmetric Synthesis: Utilized as a precursor or scaffold in catalytic asymmetric reactions to introduce specific stereocenters.
• Medicinal Chemistry Research: Employed in structure-activity relationship (SAR) studies and lead optimization processes due to its rigid, three-dimensional structure.
• Fine Chemical Production: Serves as a building block for the synthesis of specialty chemicals, agrochemicals, and other high-value compounds requiring specific stereochemistry.
• Academic & Industrial R&D: Used in methodological development and exploratory chemistry within organic synthesis laboratories.
