delta-Valerolactone Applications
1. Pharmaceutical Intermediates
delta-Valerolactone is a key raw material for the synthesis of various pharmaceuticals. For example:
Reduction produces 2,3-dihydrofuran, which is used in the synthesis of prostaglandins.
Reaction with nitrobenzene produces the antithrombotic drug Apixuban.
Reaction with D-phenylglycinol produces 3-methyl-2-piperidone, which is used in the preparation of alkaloids.
2. Materials and Polymers
The monomer can be polymerized into homopolyesters or copolymers with other monomers, with applications in:
Antifouling coatings and biodegradable adhesives
Supramolecular copolymers improve the thermal resistance and mechanical properties of materials
3. Daily Chemicals and Foods
delta-Valerolactone can be used as a fragrance intermediate in the synthesis of daily chemical products and food additives.
