One‐Pot Transformation of Carbohydrates into Valuable Furan Derivatives via 5‐Hydroxymethylfurfural

Abstract

the optimizedc onditions of solvent andb ase catalyst in hand, the one-pot dehydrationo ff ructosea nd the condensation sequencew ithv ariousk etones afforded the products in good overall yields over two steps. The scope of the process was expanded to more complex carbohydrates, such as glucose, lactose, sucrose, cellobiose, and inulin.M oreover, by fine-tuning the reaction conditions, the one-pot methodology in which we used inulin as the substrate was highly efficient if applied to variousother important reactions, such as oxidation, reduction, and Cannizzaroa nd Baylis-Hillman reactions, which rendered the corresponding furan derivatives in high overall yields.Scheme1.HMF as ap latform chemicalfor the production of valuable furanic compounds.

Towards Improved Biorefinery Technologies: 5‐Methylfurfural as a Versatile C6 Platform for Biofuels Development

“…However, these approaches have several disadvantages associated with difficult hydrogenation of hydroxy groups in HMF (and related biofuel precursors) resulting in harsh reaction conditions and low‐selectivity reduction . In addition, the chemical instability and high polarity of HMF complicate its efficient preparation from renewable feedstocks –. In this regard, development of reliable renewable chemical platforms for biofuels production is of paramount importance.…”

Hydroxymethylfurfural as an Intermediate of Cellulose Carbonization

“…5-HMF is a potential feedstock for the production of renewable plastics, but most related studies have utilized 5-HMF derivatives, such as 2,5-bis(hydroxymethyl)furan and 2,5furandicarboxylic acid. [24][25][26][27] Accordingly, information on the polymerization of 5-HMF by heating is limited. [28] Therefore, the polymerization behavior of 5-HMF was evaluated at 280°C.…”

Heterogeneous Catalytic Conversion of Sugars Into 2,5-Furandicarboxylic Acid

“…A direct one-pot, two-step conversion of inulin to FDCA was also studied where, inulin was first converted to HMF in KBr (30 mol%) and H 2 SO 4 catalyst (Wrigstedt et al, 2017 ). The resultant HMF was then oxidized using Pt/C catalyst under NaHCO 3 basic medium at 80°C and 14 h reaction time, with 44% yield of FDCA obtained.…”
