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 optimized condition, LA and anisole render 90 % conversion of former with 82 % yield of para‐substituted γ‐lactone. C−C bond formation followed by intra‐molecular esterification is witnessed in the
