Reductive amination of 2,5-diformylfuran (DFF) was used to implement the transition from bio-derived 5-hydroxymethylfurfural (HMF) to pharmaceuticals. The synthesized bis(aminomethyl)furans were utilized as buildingblocks for the construction of new derivatives with structural cores of naturally occurring biologically active compounds. Using the one-pot procedure, which included the Diels-Alder reaction
We report here the synthesis and testing of a set of 48 alumina-supportedcatalysts for hydrogenation of 5-ethoxymethylfurfural. This catalytic reaction is very important in the context of converting biomass to biofuels. The catalysts are composed of one main metal (gold, copper, iridium, nickel, palladium, platinum, rhodium, ruthenium) and one promoter metal (bismuth, chromium, iron, sodium, tin,

Hf‐, Zr‐ and Sn‐Beta zeolites effectively catalyze the coupledtransferhydrogenation and etherification of 5‐(hydroxymethyl)furfural with primary and secondary alcohols into 2,5‐bis(alkoxymethyl)furans, thus making it possible to generate renewable fuel additives without the use of external hydrogen sources or precious metals. Continuousflow experiments reveal nonuniform changes in the relative deactivation

reaction proceeds through the sequential transferhydrogenation and etherification of HMF to 2,5‐bis(alkoxymethyl)furan, a potentialbiodiesel additive, catalyzed by a Lewisacidzeolite, such as Sn‐Beta or Zr‐Beta. An alcohol is used as a hydrogen donor and as a reactant in etherification. This cascade reaction can selectively produce high yields of the biodiesel additive (>80 % yield) from HMF with the

quantum chemistry methods. For the first time, a structure-activity relationship was established in furan-yne cycloaddition for a number of different HMF derivatives. Correlations between the activation energy of the cycloaddition stage and the structure of the substrates were established by molecular modeling methods. Analysis of the concerted and stepwise mechanisms of cycloaddition in the singlet and
