Furanoate-Based Nanocomposites: A Case Study Using Poly(Butylene 2,5-Furanoate) and Poly(Butylene 2,5-Furanoate)-co-(Butylene Diglycolate) and Bacterial Cellulose [PDF]

Polymers, 2018
Polyesters made from 2,5-furandicarboxylic acid (FDCA) have been in the spotlight due to their renewable origins, together with the promising thermal, mechanical, and/or barrier properties. Following the same trend, (nano)composite materials based on FDCA could also generate similar interest, especially because novel materials with enhanced or refined ...

Structural Investigation of Poly(ethylene furanoate) Polymorphs [PDF]

Polymers, 2018
α and β crystalline phases of poly(ethylene furanoate) (PEF) were determined using X-ray powder diffraction by structure resolution in direct space and Rietveld refinement. Moreover, the α’ structure of a PEF sample was refined from data previously reported for PEF fiber.

Synthesis and Characterization of Bio-Based Polyesters: Poly(2-methyl-1,3-propylene-2,5-furanoate), Poly(isosorbide-2,5-furanoate), Poly(1,4-cyclohexanedimethylene-2,5-furanoate) [PDF]

Materials, 2017
In the present study, three new biobased furanoate polyesters with potential use in food packaging applications, named poly(isosorbide furanoate) (PIsF), poly(methyl-propylene furanoate) (PMePF) and poly(1,4-cyclohexane-dimethylene 2,5-furanoate) (PCHDMF) were synthesized.

Synthesis and antitubercular activity evaluation of 4-furano-coumarins and 3-furano-chromones

Synthetic Communications, 2018
The synthesis of novel 4-furano-coumarins and 3-furano-chromones has been achieved using silver-mediated oxidative C–H/C–H functionalization of 4-ethynylcoumarin/3-ethynylchromone with ethyl acetoacetate in 80%–90% and 82%–90% yields, respectively. The structure of the synthesized compounds was established on the basis of their spectral data analysis ...

Enhanced Selectivity of Chalcogen Bonding over Halogen Bonding Catalyzed C‐glycosylation Through Differentiated Intermediate Activation

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
By harnessing chalcogen bonding (ChB) catalysis, an exclusive access into a highly stereoselective strain‐release C‐glycosylation pathway was discovered. This was surprisingly not replicable by the conceptually similar halogen bonding (XB) catalysis.
