This review surveys sustainable one-pot conversion methods of cellulose into two very
important platform chemicals such as 5-hydroxymethylfurfural and isosorbide retaining
applications in many fields. Various new techniques based on such as ionic liquids, acid
functionalized mesoporous materials, organic acids, functionalized nanoparticles, and
mechanocatalytic depolymerization was discussed in detail for the very important direct
conversion of cellulose to 5-hydroxymethylfurfural. More emphasis is given on a
comparative analysis of recently developed all successful methods for 5-
hydroxymethylfurfural production from cellulose in terms of efficiency, selectivity and
cost-effectiveness. The article also complements on the promising extraction methods for
the 5-hydroxymethylfurfural using special solvents. The importance of another very
interesting platform chemical, i.e. isosorbide is also addressed. Several factors of cellulose
to isosorbide transformation including metal nanoparticle size, crystallinity order of the
cellulose, and extraction medium which controls the rate of conversion and product
distillation have been addressed. The article also surveys the potential discoveries in onepot
conversion of cellulose into biofuels. The strategies of cellulose and lignocellulose
conversions to compounds with liquid fuel’s features have been discussed focusing on the
production of g-valerolactone as important intermediates to access liquid hydrocarbons
and valeric esters. Cellulose value-chain for the direct conversions to liquid fuels (e.g.
cellulose to levulinic acid platform to obtain valeric biofuels) by using supported nanostructured
metal catalysts are emphasized. Overall an analysis of the main prospects and
constraints related to the several conversion routes are presented including the critical
thinking on the technical barriers, commercial promise, and environmental issues.
