Bio‐available Solvent Cyrene: Synthesis, Derivatization, and Applications

The development of green solvents is one of the key tenets of Green Chemistry as solvents account for the majority of waste stemming from the production of the chemicals on which we have all come to rely. An important class of solvents is the dipolar aprotics, which include N,N-dimethylformamide (DMF) and N-methyl-2-pyrrolidone (NMP). In addition to being derived from non-renewable resources, these solvents are also under increased regulatory pressures that will limit their industrial applications. This Concept concerns the bio-available solvent Cyrene (dihydrolevoglucosenone) as a potential replacement for toxic dipolar aprotic solvents. An emphasis is placed on examining the strengths and weaknesses of Cyrene as a solvent and is accomplished by looking at the synthesis, derivatization, and application in synthetic protocols of Cyrene. With respect to the Twelve Principles of Green Chemistry, this Concept describes a bio-available solvent that should have a disruptive effect on the use of traditional industrial dipolar aprotic solvents.

“…A thorough study of the relevant variables of the pyrolytic process has demonstrated that temperature, pressure and catalyst concentration, heat and mass transfer are the main factors. It has been reported that the acid‐catalyzed pyrolysis process allows increasing the selectivity towards levoglucosenone, when using glucose, cellulose or birch and pine wood among different biomass sources, and phosphoric acid as a catalyst, under conventional thermal pyrolysis , . The use of solid superacids and zeolites as acid catalysts was also investigated, as well as the effect of ionic liquids .…”

The need to find sustainable alternatives to reduce the dependence on fossil sources has led to significant research efforts on the conversion of biomass into platform chemicals. Modern organic chemistry requires easily obtainable chiral building blocks that show high chemical versatility for their application in the synthesis of enantiopure compounds. The selective pyrolytic conversion of cellulose or cellulose‐containing materials produces levoglucosenone, a highly functionalized chiral structure. This compound has been innovatively used as a template for the synthesis of key intermediates of biologically active products and for the preparation of chiral auxiliaries, catalysts, and organocatalysts for their application in asymmetric synthesis.

“…Cheaper crude oil makes the pursuit of biofuel less lucrative and jeopardizes the pursuit of biorefining. This could, however, be overcome by expanding the product repertoire of a biorefinery through biomass conversion to platform chemicals, analogous to a petrochemical refinery . Indeed, even petrochemical refineries earn half of their revenue from a significantly smaller business volume of chemicals (~16%) compared to that of oil (76%) .…”

The cellulosic component of lignocellulosic biomass can be converted to commercially valuable platform chemicals through pyrolysis provided it is effectively controlled and optimized. This review first discusses the underpinning kinetics and mechanism of cellulose pyrolysis to identify target platform chemicals. Platform chemicals like 5‐hydroxymethyl furfural, 5‐chloromethyl furfural, and levoglucosenone, which are potentially amenable to the pyrolytic conversion of cellulose, are then elucidated. There are laboratory and large‐scale reactor technologies available for converting biomass to bio‐oil but they have not been comprehensively investigated for producing platform chemicals through pyrolysis. This review critically evaluates different reactor types available for developing the catalytic pyrolysis process for converting cellulosic component of biomass to platform chemicals. The fluidized bed reactor stands out as the most suitable reactor technology for the catalytic pyrolysis of cellulose to platform chemicals owing to attributes like short residence time, high heating rate, uniform mixing, efficient heat transfer, and scalability of operations. This article provides perspective on the implementation of this technology for the pyrolysis of the cellulosic component of biomass to platform chemicals. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd
