Description

3-Buten-2-One, 4-(3-Methyloxiranyl)-, [2S-[2Alpha(E),3Beta]]- (9Ci) is a high-purity, stereochemically defined chiral building block featuring both an α,β-unsaturated ketone and an epoxide functional group. This unique bifunctional structure makes it a critical intermediate for the synthesis of complex, biologically active molecules, offering precise control over stereochemistry in downstream reactions. It is primarily utilized by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs), agrochemicals, and other fine chemicals where specific stereochemistry is paramount for efficacy.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the asymmetric synthesis of complex drug candidates, particularly in oncology, antiviral, and anti-inflammatory research.
• Agrochemical Synthesis: Used in the production of advanced, stereospecific pesticides and herbicides where the specific enantiomer is crucial for activity and environmental safety.
• Fine Chemical Building Block: Serves as a versatile precursor in organic synthesis for creating natural product analogs, flavors, and fragrances with defined stereocenters.
• Academic & R&D: Employed in methodological chemistry research for developing new catalytic asymmetric reactions and studying epoxide ring-opening kinetics.
• Material Science Research: Potential monomer or cross-linker for developing novel polymers with specific optical or mechanical properties derived from its rigid, functionalized structure.
