Description

Cyclopentanone, 2-[(2-Propenyloxy)Methyl]-, (2S)- (9Ci) is a chiral, functionalized cyclopentanone derivative featuring an allyloxy methyl side chain. This compound serves as a valuable advanced pharmaceutical intermediate (API) and a versatile chiral building block in asymmetric synthesis. It is primarily required by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for constructing complex, optically active molecules.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly those targeting central nervous system (CNS) disorders and other therapeutic areas.
• Asymmetric Synthesis: Utilized as a chiral precursor in stereoselective reactions, including alkylations, aldol condensations, and Michael additions, to introduce the cyclopentanone scaffold with defined stereochemistry.
• Agrochemical Research: Serves as a building block for developing novel, optically active pesticides and herbicides with enhanced efficacy and selectivity.
• Ligand and Catalyst Development: Used in the preparation of chiral ligands and organocatalysts for catalytic asymmetric transformations.
• Flavor and Fragrance Chemistry: Potential intermediate for the synthesis of complex, naturally occurring odorants and flavor compounds with specific stereochemical profiles.
• Material Science Research: Exploration as a monomer or cross-linking agent for creating specialized polymers with unique optical or mechanical properties.
