Description

2-Azabicyclo[2.2.0]Hex-5-En-3-One,2-Butyl-,(-)-(9Ci) CAS NO 470661-05-3 is a high-purity, chiral bicyclic lactam building block of significant interest in advanced organic synthesis. Its constrained, nitrogen-containing framework makes it a valuable precursor for constructing complex molecular architectures with precise stereochemistry. This compound is primarily utilized by research and development chemists in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of new drug candidates, particularly for central nervous system (CNS) and anti-infective agents.
• Agrochemical Synthesis: Used in the creation of novel, stereochemically defined pesticides and herbicides with enhanced efficacy and selectivity.
• Catalyst & Ligand Development: Acts as a precursor for novel chiral catalysts and ligands used in asymmetric synthesis.
• Academic & Industrial Research: Employed in methodological studies and the synthesis of complex natural product analogs and specialty materials.
• Fine Chemical Production: Integral to the multi-step synthesis of high-value, optically active fine chemicals and flavors/fragrances.
