Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Discovery of Some New Heterocyclic Systems from Carbene‐Based Reactions of Indigo and N‐Methyl Derivatives

European Journal of Organic Chemistry, EarlyView.
Accessing new heterocyclic structural space on exposure of indigo‐based substrates to carbene or carbenoid reactive intermediates is the key focus of this work. A number of unprecedented heterocyclic products have been discovered and their structures characterized.
