Description

(S)-4-(1-Isopropyl)-3-(1-Oxobutyl)-2-Oxazolidinone is a high-purity chiral oxazolidinone derivative, a critical building block in asymmetric synthesis. Its value lies in its role as a highly effective chiral auxiliary, enabling the stereoselective construction of complex molecules with high enantiomeric excess. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and fine chemical industries developing novel active ingredients and advanced intermediates.

Application

• Pharmaceutical Intermediate: A key chiral auxiliary in the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs), particularly for cardiovascular and central nervous system (CNS) drugs.
• Asymmetric Synthesis: Used in Evans aldol reactions and other stereocontrolled transformations to install chiral centers with high diastereoselectivity.
• Agrochemical Research: Employed in the development of chiral herbicides, fungicides, and pesticides where specific stereochemistry is required for optimal activity and reduced environmental impact.
• Fine Chemical Production: Serves as a precursor or auxiliary in the manufacture of specialty chemicals, flavors, and fragrances requiring precise stereochemical control.
• Academic & Process Chemistry: A valuable tool in research laboratories and for scaling up synthetic routes in process chemistry for pilot and commercial production.
