Biobased Poly(dodecylene Furanoate) with Inherent Advantages in Performance and Circularity

open access: yesChemSusChem, EarlyView.
Thanks to its inherent biomass furan motif that can promote polymer H‐bonding networks, biobased polyester PDDF is shown to exhibit advantages not only in performance (e.g., superior modulus, crystallinity, gas barrier properties) but also in end‐of‐life management (biodegradability and closed‐loop chemical circularity), as compared to petroleum‐based ...

Upcycling Food Waste: Ursolic Acid as Sustainable Feedstock

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This study presents a sustainable strategy to access 24 ursane‐type natural products from ursolic acid, derived from apple pomace waste. The method enables short syntheses (1–12 steps) with high yields (up to 98%). By upcycling food waste into valuable bioactive compounds, this work exemplifies green chemistry and supports circular economy principles ...

Expanding the Chemical Space of Sugar Frameworks by Quaternization of the Anomeric Carbon Atom

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Novel C,C and C,N bifunctional fucosides are stereoselectively obtained starting from a common anomeric bromide intermediate. The developed methodology expands the chemical space at the anomeric position of fucose and supports future applications in glycomimetics design.
