A golden opportunity : A highly robust catalyst system consisting of gold nanoparticles supported on acid‐tolerant ZrO 2 promoted the conversion of biomass‐derived levulinic acid ( 1 ) and formic acid ( 2 ) into γ‐valerolactone without the use of an external H 2 supply (see scheme, red). The Au/ZrO 2 catalyst was also used for the direct one‐pot synthesis of highly valuable pyrrolidone derivatives from 1, 2 , and primary amines (see scheme, blue).
