Borane catalysed ring opening and closing cascades of furans leading to silicon functionalized synthetic intermediates

Nature Communications, 2016
Furans are attractive staring materials in organic chemistry, due to the ease of functionalisation and sourcing from renewable feedstocks. Here the authors show the ring opening of furans to silane intermediates, followed by further conversion to ...

Oxidation of azidoalkyl furans

Tetrahedron Letters, 2016
Abstract The oxidation reactions of various azidoalkyl furans were explored under different conditions to access structurally complex compounds from simple starting materials in an operationally simple, single step reaction. The strategically placed azide functional groups on the alkyl chain of the furan led to the discovery of a new and simple ...

Liquid‐phase oxidation of furfural catalyzed by magnetically separable metal oxide nanoparticles deposited on silica gel

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Oxidation of furfural (FF), a bio‐based platform chemical, was investigated using a range of iron‐, vanadium‐ and iron–zinc‐oxalates supported on silica gel (FeVOx@silica and FeZnOx@silica, respectively) as precursor for FeV@silica and FeZn@silica oxide catalysts and H2O2 as a green oxidant.

Catalytic Conversion of Glucose and Chlorella Sp. Into Furans in the Presence of Niobium Oxide

Chemical Engineering Transactions, 2023
A series of Nb2O5 solid catalysts have been prepared to be used for the catalytic dehydration of glucose and sugars from algae Chlorella sp. into added value furans. The glucose transformation gave rise to 5-hydroxymethylfurfural (5-HMF).

Formation of furan and furan derivatives in baby food products

Food Chemistry
A comprehensive analysis of 89 commercial baby food samples showed the highest levels of furan in ready-to-eat full meals and vegetable purees (12-118 μg/kg). The alkylated furans (2- and 3-methylfuran, 2-ethylfuran, 2-pentylfuran) were predominantly found in these baby food categories.
