Chemo‐ and Regioselective Synthesis of Arylated γ‐Valerolactones from Bio‐based Levulinic Acid with Aromatics Using H‐β Zeolite Catalyst

Abstract: Catalytic coupling of biomass-based molecules to value-added chemical intermediates is an interesting area in biomass research. Arylated γ-valerolactones (Agvls), promising pharmaceutical intermediates that have significant biological activity, are primarily synthesized currently through petro-route. In this paper, we report successful biomass-based synthesis of Agvls using levulinic acid (LA) and oxygen or sulphur-substituted aromatics over H-β zeolite as catalyst under solvent-free conditions. Under optimize… Show more

“…These reactions include hydrocyclization, hydrogenation, dehydration, oxidation, reductive amination, halogenation, alkylation, and condensation, as illustrated in Scheme 3 . LA can act as an intermediate in the synthesis of many compounds, including arylated cyclic lactones, alkylated lactones, ketals, halo substituted keto carboxylic acids, amides (cyclic/acyclic), valerates, valeric acids, aliphatic alcohols, acid halides, 1,4-diketones, alkanes, alkenes, cyclic ethers, and numerous other derivatives [ 24 , 25 , 26 , 27 ]. LA contains oxygen functionality (oxo and carboxylic), leading to the production of numerous high-value products through hydrocyclization and hydrodeoxygenation reactions [ 28 ].…”

“…Lignocelluloses and triglycerides are primary sources of bioenergy [1] . Utilization of bio‐based fuels and materials leads to decrease in environmental emissions and also helps in improving the indigenous economy [2,3] . Lignin obtained from biomass has less commercial applications to‐date; at present, globally various researchers are working on its value‐addition [4] .…”
