Synthesis of Sulfur Heterocycles by Palladium‐Catalyzed Cyclization

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
In spite of the well‐known palladium thiophilicity, sulfur‐containing acyclic substrates may efficiently undergo several different kinds of palladium‐catalyzed cyclization processes leading to highly important sulfur heterocycles in one synthetic step. Advances in this challenging and stimulating field of research are presented in this review.

Catalytic Hydrogenation of Lignin‐Derived Aromatics With Rhodium Oxide in Water

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The easily available, easy‐to‐handle rhodium(III) oxide, Rh2O3, is shown to be a competent catalyst for arene hydrogenation, including chemoselective reduction of α,β‐unsaturated aryl ketones. Catalytic arene hydrogenation offers a direct pathway to saturated carbocycles. It can also be exploited to upgrade lignin‐derived aromatics.

Understanding protein–flavor interactions: Factors, characterization techniques, and the effect of processing

open access: yesFood Biomacromolecules, EarlyView.
Abstract The perception of flavor in a food system depends on its release from the protein matrix. Apart from hydrogen bonding, hydrophobic interactions and van der Waal's forces, the formation of covalent adducts between the flavor and protein highly impacts the release of flavor from the protein matrix.
