Gem‐Diboronic Acids: A Motif for Anion Recognition in Competitive Media

open access: yesAngewandte Chemie, EarlyView.
Gem‐diboronic acids are an anion recognition motif that provides strong and directional binding to oxoanions in aqueous media. This motif provides a selectivity profile that is distinct from other anion recognition groups, and binding affinities that are superior to those of simple amides and (thio)ureas.

Discovery and Biosynthesis of Celluxanthenes, Antibacterial Arylpolyene Alkaloids From Diverse Cellulose‐Degrading Anaerobic Bacteria

open access: yesAngewandte Chemie, EarlyView.
The structure and biosynthetic origin of the enigmatic “yellow affinity substance” (YAS) from the anaerobe thermophile Clostridium thermocellum (now: Acetivibrio thermocellus) were elucidated. YAS is a complex of unusual antibacterial arylpolyene alkaloids (celluxanthenes) that are produced by various cellulolytic anaerobes.

Unnatural Triggers Converted From Tetrazine‐Attached Sialic Acid for Activation of Optoacoustic Imaging‐Guided Cancer Theranostics

open access: yesAngewandte Chemie, EarlyView.
Tetrazine precursors (SiaTz) based on a nonO‐acetylated sialic acid scaffold are rationally designed and synthesized, which can be efficiently converted into unnatural tetrazine (Tz) triggers on cancer cell surfaces via metabolic glycoengineering. These Tz triggers activate theranostic agents for multispectral optoacoustic tomographic (MSOT) imaging ...

Environmental History is Transferred via Minerals Altering Formose Reaction Pathways

open access: yesAngewandte Chemie, EarlyView.
We study the influence of minerals on the formose reaction. We found that different minerals have distinct impact on the network outcome effects, that change over sequential batch reactions, demonstrating a history effect. Finally, we show that when minerals are first incubated with the aqueous catalysts, they subsequently allow for formation of ...

Cathodic Hydroxide Ions Induce Tetrose Formation during Glycolaldehyde Electroreduction to Alcohols: A Potential CO2‐to‐Carbohydrate Pathway

open access: yesAngewandte Chemie, EarlyView.
The glycolaldehyde electrolysis mechanism to alcohols and tetroses is comprehensively studied. Novel insights on the role of glycolaldehyde in the late stages of the overall CO2 reduction reaction pathways to ethanol and ethylene glycol on copper are presented.
