Photochemical Conversion of Indazoles into Benzimidazoles

open access: yesAngewandte Chemie International Edition, EarlyView.
We present a photochemical strategy for transforming 1H‐ and 2H‐indazoles into benzimidazoles, enabling heteroaromatic interconversion under mild conditions. This approach, grounded in a two‐step mechanism of excited‐state tautomerization and photochemical rearrangement, offers broad scope, high yields, and functional group tolerance, expanding the ...

The Chemistry and Biology of the Tetrodotoxin Natural Product Family

open access: yesAngewandte Chemie International Edition, Accepted Article.
Tetrodotoxin is a neurotoxic marine alkaloid, first isolated in 1909 from pufferfish and named after the biological order tetraodontiformes. Since its structural elucidation in 1964, it has attracted the interest of synthetic organic chemists due to its exceptional polarity, complex architecture, and important biological activity.

Coordinative Ring‐Opening Polymerization of Limonene Carbamate towards Phosgene‐ and Isocyanate‐Free Polyurethane

open access: yesAngewandte Chemie International Edition, Accepted Article.
This study presents a phosgene‐ and isocyanate‐free route for the synthesis of polyurethanes using (R)‐limonene as a bio‐based starting material. The synthesis of the cyclic limonene‐based carbamate monomer LU is achieved in high yields using dimethyl carbonate as a sustainable, less hazardous phosgene surrogate and is verified by NMR, SC‐XRD, ESI‐MS ...

Pharmacophore-based design and discovery of (−)-meptazinol carbamates as dual modulators of cholinesterase and amyloidogenesis

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2017
Multifunctional carbamate-type acetylcholinesterase (AChE) inhibitors with anti-amyloidogenic properties like phenserine are potential therapeutic agents for Alzheimer’s disease (AD).

Photo‐controlled Release of Urea Enables the Detection of Urea‐Urease Intermediates by cryo‐FTIR

open access: yesAngewandte Chemie International Edition, Accepted Article.
Caged compounds are a valuable tool to photocontrol the release of enzymatic substrates in a reaction. For example, caged urea molecules were proposed to control urea delivery to urease reactions and aid the determination of the catalytic mechanism of this enzyme.
