Pd/C‐Catalyzed Hydrogenation of CF3‐, CF2H‐, and CF2CO2Et‐containing Pyridines: A Robust Method for Highly Functionalized containing Piperidines

Angewandte Chemie, EarlyView.
A robust and efficient method to access diversely functionalized fluorinated piperidines was developed. The approach features the hydrogenation of polysubstituted pyridines bearing CF3, CF2H, and CF2CO2Et substituents using an inexpensive, readily available heterogeneous Pd/C catalyst under air‐ and moisture‐tolerant conditions, offering an appealing ...

Funktionalisierung von Peptiden auf der festen Phase im späten Synthesestadium

Angewandte Chemie, EarlyView.
Peptidmodifikationen sind für die Kontrolle der Eigenschaften von Peptidwirkstoffen von entscheidender Bedeutung. Daher sind Strategien, die einen effizienten und schnellen Einbau nicht‐kanonischer Modifikationen in Peptide in Parallelformaten ermöglichen, sehr gefragt.

Spatial Orientation‐Dependent Double Hydrogen Bond/Photoredox Cooperative Catalysis in Metal–Organic Frameworks

Angewandte Chemie, EarlyView.
We report a heterogeneous double hydrogen bond/photoredox synergistic catalysis, wherein the flexibility and spatial orientation of catalytic centers, rather than catalyst activity, play a dominant role in catalytic performance. ABSTRACT Catalyst activity is typically the primary priority in designing a catalytic system. The higher catalyst activity is

Katalytischer Schwefelatomtransfer vermittelt durch einen Bis(disulfido)‐Titankomplex

Angewandte Chemie, EarlyView.
Mehrelektronentransformationen mit Titan sind aufgrund der limitierten Zugänglichkeit niedervalenter Vorstufen bislang nur unzureichend untersucht. Die Vier‐Elektronen‐Aktivierung von elementarem Schwefel durch einen Ti(IV)‐Komplex führt zu einem seltenen Bis(disulfido)‐Titankomplex, der die effiziente katalytische Synthese von Isothiocyanaten aus ...
