Precision Switching and Coupled Motion in a [3]Rotaxane Molecular Machine
Angewandte Chemie, EarlyView.A [3]rotaxane, composed by two crown ether macrocycles and an axle presenting three recognition sites, is operated through both chemical and electrochemical stimuli. The position of the macrocycles is precisely controlled by sequential stimulation and the processes are fully reversible. The characterization of the system revealed the macrocycles affect

Angewandte Chemie, EarlyView.Die Kontrolle biologischer Systeme mit organischen Chromophoren hat sich zu einer vielversprechenden Strategie entwickelt und findet Anwendung von der chemischen Biologie bis hin zur Medizin. Die Komplexität von In‐vivo‐Systemen lässt sich jedoch nicht mit nur einer einzigen Lichtwellenlänge adäquat abbilden.

Angewandte Chemie, EarlyView.Photochemically generated phosphoryl radicals from iminyl phosphines enable strain‐release addition to azabicyclobutanes, providing access to elusive N‐phosphoryl azetidines. Combined experimental, computational, and EPR studies reveal an unconventional water‐assisted photoredox pathway.

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.
