“…Aiming to achieve this goal, Palkovits’ group report an efficient solvent‐free approach for the hydrogenation of α‐AL by using Ru/C as a catalyst (Scheme ) . Their approach involves the use of mild conditions, and the reactions can be conducted at room temperature in batch and open‐reactor setups.…”

The upgrading of biomass‐derived compounds has arisen in recent years as a very promising research field in both academia and industry. In this sense, a lot of new processes and products have been developed, often involving levulinic acid as a starting material or intermediate. In the last few years, though, other scaffolds have been receiving growing attention, especially, angelica lactones. Considering these facts and the emergent applications of said molecules, in this review we will discuss their preparation and applications; the use of these frameworks as starting materials in organic synthesis to produce potential bioactive compounds will be covered, as will their use as a foundation to highly regarded compounds such as liquid alkanes with prospective use as fuels and polymers.

“…Conversion of LA is carried out by the catalytic hydrogenation of LA using a hydrogen source [14]. Hydrogenation of LA to GVL occurs via either dehydration to angelica lactone (AL) followed by its reduction or via reduction of LA to 4-hydroxy valeric acid (4-HVA) and subsequent dehydration [15].…”

“…[23][24][25] Nevertheless, the formation of water during esterification prohibits complete conversion. [31][32][33] Herein we study the preparation of LAE starting from α-AL and LA using different alcohols. This stresses the need for new protocols in which LAE can be prepared in high yield without costly separation steps.…”

Butyl levulinate was prepared starting from α-angelica lactone and butanol over Amberlyst® 36. Different reaction conditions were optimized, which resulted in full conversion and 94% selectivity toward the ester at 75 °C. A reaction network analysis reveals pseudo-butyl levulinate and levulinic acid as intermediates in the preparation of butyl levulinate. The mild protocol was successfully applied for different alcohols and compared with the esterification of levulinic acid. Overall, this study identifies α-angelica lactone as a better candidate than levulinic acid for the heterogeneously catalysed preparation of levulinic acid esters. A catalyst screening shows that also zeolites and zirconia-based catalysts are able to catalyse the reaction. However, the transformation of the intermediate pseudo-butyl levulinate into butyl levulinate requires acid sites of sufficient strength to proceed
