Description

(Z)-3-Methyl-4-[(2S)-Tetrahydro-3α,4α-Dihydroxy-5β-[[(2S,3S)-3α-[(1S,2S)-2-Hydroxy-1-Methylpropyl]Oxiran-2β-Yl]Methyl]-2H-Pyran-2β-Yl]-2-Butenoic Acid Ethyl Ester is a high-purity, complex chiral intermediate of significant importance in advanced organic synthesis. Its intricate stereochemistry and functional groups make it a critical building block for the development of novel, biologically active molecules. This compound is essential for research and development chemists in the pharmaceutical and fine chemical industries, particularly for projects involving natural product synthesis and drug discovery.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of new active pharmaceutical ingredients (APIs), especially in complex therapeutic areas.
• Natural Product Synthesis: Used in the total or semi-synthesis of complex natural products with potential medicinal value.
• Asymmetric Catalysis Research: Serves as a sophisticated substrate or ligand precursor in the development of new catalytic methodologies.
• Fine Chemical Production: Employed in the multi-step synthesis of specialty chemicals, flavors, and fragrances requiring high stereochemical purity.
• Biochemical Research: Potential use as a probe or inhibitor in enzymatic studies due to its complex, sugar-like pyran and epoxide motifs.
• Process Chemistry Development: Used for scaling up synthetic routes and optimizing production processes for complex molecules in pilot plants.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider the use of desiccants.
