애플리케이션
δ-Valerolactone (tetrahydro-2H-2-pyranone or δ VL) can be used as a monomer unit in the synthesis of poly(δ-valerolactone)s poly(conjugated ester)s via ring-opening polymerization.
It can also be used as a starting material in the synthesis of (+)-guadinomic acid , sodium δ-hydroxyvalerate , methyl δ-hydroxyvalerate , and 5-hydroxyvaleraldehyde.

A palladium-catalyzed decarboxylative cyclopropanation of γ-methylidene-δ-valerolactones with aromatic aldehydes has been developed to give 4-oxaspiro[2.4]heptanes with high selectivity. The site of nucleophilic attack to a π-allylpalladium intermediate has been controlled with a sterically demanding phosphine ligand. The course of the

gamma-Butyrolactone, unlike delta-valerolactone, does not polymerize despite a strain energy of approximately 8 kcal mol-1 which could be relieved by opening the s-cis lactone ester bond to an s-trans ester bond in the polymer. To explain this anomaly, we have

Biodegradable polyurethane urea (PUU) elastomers are ideal candidates for fabricating tissue engineering scaffolds with mechanical properties akin to strong and resilient soft tissues. PUU with a crystalline poly(ε-caprolactone) (PCL) macrodiol soft segment (SS) showed good elasticity and resilience at small
