Description

1H,3H-Pyrrolo[1,2-C]Oxazole-1,3-Dione,5-Ethyltetrahydro-,(5S-Cis)-(9Ci) is a high-purity, stereochemically defined heterocyclic compound, serving as a critical chiral building block and intermediate in advanced organic synthesis. Its value lies in its unique fused oxazole-pyrrolidine structure, which provides a rigid scaffold for constructing complex molecules with precise three-dimensional orientation. This compound is essential for research and development chemists in the pharmaceutical and agrochemical industries, particularly for the synthesis of novel active ingredients where stereochemical control is paramount.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of new active pharmaceutical ingredients (APIs), especially in neurological and anti-infective drug candidates.
• Agrochemical Synthesis: Used in the creation of advanced, stereoselective pesticides and herbicides where specific isomer activity is required.
• Asymmetric Catalysis Ligand Precursor: Serves as a starting material for developing novel chiral ligands used in asymmetric hydrogenation and other catalytic processes.
• Fine Chemical Production: Employed in the multi-step synthesis of complex flavors, fragrances, and specialty performance chemicals.
• Academic & Contract Research: A valuable tool for methodological studies in organic chemistry and for contract research organizations (CROs) working on client-specific synthetic routes.
• Material Science Research: Investigated as a monomer or precursor for novel polymers with specific optical or electronic properties.
