(R)-tert-Butyl azepan-3-ylcarbamate(CAS: 1354351-56-6)

(R)-tert-Butyl azepan-3-ylcarbamate is a colorless to pale yellow liquid with a molecular weight of approximately 244.32 g/mol. It has a specific gravity of 0.972 and is moderately soluble in water but highly soluble in common organic solvents like ethanol and acetone. This compound exhibits moderate reactivity towards nucleophiles and can undergo substitution reactions. It crystallizes in the monoclinic system.

(R)-tert-Butyl azepan-3-ylcarbamate is typically synthesized through a multistep process involving protection of the azepane ring, followed by coupling with tert-butyl isocyanide. The reaction is carried out in the presence of a suitable base such as triethylamine and catalyzed by a phase transfer catalyst. The yield is generally around 70-80%, and the selectivity is high.

(R)-tert-Butyl azepan-3-ylcarbamate is primarily used in the pharmaceutical and polymer industries. It serves as a key intermediate in the synthesis of various biologically active compounds. Additionally, it is explored for its potential applications in sensor technology and as a precursor in the development of new materials.

When handling (R)-tert-Butyl azepan-3-ylcarbamate, it is essential to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work in a well-ventilated area or fume hood to prevent inhalation or skin contact. Spills should be handled with caution, and the area should be cleaned with appropriate solvents. Refer to the safety data sheet (SDS) for detailed instructions and emergency procedures.
