γ-Valerolactone (GVL) or gamma-valerolactone is an organic compound with the formula C 5 H 8 O 2. This colourless liquid is one of the more common lactones. GVL is chiral but is usually used as the racemate. It is readily obtained from cellulosic biomass and is a …

Gamma-valerolactone (GVL) derived from lignocellulosic biomass can be used as a value-added platform chemical for the production of biofuels, fuel additives, and polymers. Ethyl levulinate (EL) or levulinic acid (LA) can be converted to GVL through the heterogeneous catalytic hydrogenation.

Gamma-valerolactone is a butan-4-olide that is dihydrofuran-2 (3H)-one substituted by a methyl group at position 5. It has been found in the urine samples of humans exposed to n-hexane. It has a role as a flavouring agent and a human xenobiotic metabolite.

GVL is a green solvent used in Fmoc-based solid-phase peptide synthesis. It is susceptible to ring opening in the presence of bases such as piperidines, which are used to remove the Fmoc protecting group. Here we studied the formation of the corresponding acyl piperidides by time-dependent monitoring using NMR.

Jul 18, 2024 · A novel green solvent, γ-valerolactone (GVL), efficiently facilitates the photocatalytic activation of C−H bonds in benzylic compounds. Mechanistic studies reveal that GVL′s high dielectric constant ...

Feb 27, 2025 · γ-Valerolactone?(GVL) is a dipolar aprotic, bio-based, fully degradable, non-toxic green solvent and has been aligned with "Safer Solvent and Auxiliaries"," Use of Renewable Feedstocks and Design for Degradation".

Oct 31, 2024 · \ (\gamma\) -Valerolactone (GVL) is a colorless liquid with a bp of 207–208 °C. It is a chiral molecule but usually used as the racemate solvent. As a naturally occurring chemical with a pleasant fruit smell, it can be used as a fragrance additive in daily products.

Oct 7, 2024 · In this study, we demonstrate that novel and safe green solvents, such as γ-valerolactone (GVL), can significantly enhance the performance of semiconductor photocatalysis for C-H bond activation. Non-specific solvent-solute interactions are the primary contributors to increased photocatalytic activity in the self-coupling of benzylic compounds.
