Description

2H-Pyran,2-Ethoxy-3,4-Dihydro-4-Phenyl-,(2S,4S)-(9Ci) is a chiral, substituted dihydropyran derivative, a valuable synthetic intermediate in advanced organic chemistry. Its defined stereochemistry and functionalized pyran ring make it a critical building block for constructing complex molecular architectures with high enantiomeric purity. This compound is essential for researchers and process chemists in the pharmaceutical and fine chemical industries, particularly for developing active pharmaceutical ingredients (APIs) and novel chiral ligands.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the synthesis of potential drug candidates, especially for central nervous system (CNS) and cardiovascular targets.
• Asymmetric Catalysis: Used as a precursor for developing novel chiral ligands and organocatalysts for enantioselective synthesis.
• Natural Product Synthesis: Acts as a building block in the total synthesis of complex natural products containing oxygenated heterocycles.
• Material Science Research: Investigated as a monomer or precursor for creating specialized polymers with unique optical or electronic properties.
• Agrochemical Development: Employed in research for creating new chiral active ingredients for crop protection agents.
• Academic & R&D: A valuable tool for methodological studies in organic synthesis and stereochemistry at research institutions.
