Modular Access to α‐Tertiary Amines: Electrochemical Tandem Di‐Functionalization of Olefins With Ammonia Surrogates and Amino Acids

Angewandte Chemie, EarlyView.
A metal‐ and oxidant‐free electrochemical multicomponent di‐functionalization strategy that rapidly converts 1,1‐disubstituted alkenes into α‐tertiary primary amines with simultaneous installation of bio‐relevant sulfur or selenium motifs was devised for late‐stage functionalization. ABSTRACT Quaternary carbon centers, especially those bearing nitrogen,

Durch anomere Amide ermöglichte divergente Synthese unsymmetrischer Harnstoffe, Carbamate, Thioester und Amide aus Aldehyden

Angewandte Chemie, EarlyView.
Eine divergente Aldehyd‐Funktionalisierungssequenz, ermöglicht durch ein anomeres Amid, erlaubt den Ein‐Topf‐Zugang zu unsymmetrischen Harnstoffen, Carbamaten, Thiocarbamaten, Thioestern und Amiden. Entscheidend für diese Transformation ist die Bildung von N‐Boc‐Hydroxamat‐Intermediaten, die als Plattformen für eine orthogonale Aktivierung über Lossen ...

π‐Extended COUPY Fluorophores for Targeted Near‐Infrared Fluorescence and Lifetime Imaging in Live Cells

Angewandte Chemie, EarlyView.
π‐Extended COUPY dyes, obtained by vinylogation of coumarin‐based COUPY scaffolds, shift absorption, and emission deep into the NIR region while preserving compactness and synthetic accessibility. These bright, photostable dyes enable live‐cell imaging, FLIM, and site‐specific peptide conjugation, offering a modular platform for targeted bioimaging and

Engineering BN‐Doped Open‐Shell Polycyclic Hydrocarbons for Enhanced Photothermal Conversion and Therapy

Angewandte Chemie, EarlyView.
Two novel bonded BN‐doped polycyclic hydrocarbons BN‐Dira and BN‐Tetra with open‐shell character were rationally designed and synthesized. Their molecular structures were unambiguously confirmed by crystallographic analysis. Facilitated by their intense absorption in the NIR region, high PCE (83.6%) and good photothermal stability, BN‐Dira and BN‐Tetra

Functional and Network PHAs via Stereoselective Polymerization and Tailored Post‐Transformation

Angewandte Chemie, EarlyView.
Catalyst‐controlled stereoselective (co)polymerization of functionalized lactones produces vinyl‐, allyl‐, and propargyl‐functionalized PHAs with high syndiotacticity and a broad applicable temperature window, which can be further transformed into crosslinked PHA thermosets, elastic supramolecular networks, and functional grafts.
