Steuerbare endo/exo‐Selektivität in direkten katalytisch‐ asymmetrischen 1,3‐dipolaren Cycloadditionen mit polyfunktionellen Lewis‐Säure‐/Azolium‐Aryloxid‐Katalysatoren

Angewandte Chemie, EarlyView.
Ein neuartiges Konzept für katalytische asymmetrische 1,3‐dipolare Cycloadditionen mit Iminoestern verwendet modulare polyfunktionelle Lewis‐Säure‐/Azolium‐Aryloxid‐Betain‐Katalysatoren, die die endo‐ und exo‐Selektivität durch Anpassungen des Metallzentrums, des Azoliums und der Sterik steuern. DFT‐Studien zeigen eine nahezu perfekte räumliche Passung

Controlling the Helicity and Handedness of Polyaromatics with Isobenzofuranophane

Angewandte Chemie, EarlyView.
Isobenzofuranophanes are introduced as helical synthons that enable late‐stage helicity induction and control in polyaromatics. This remote tethering approach allows precise control over the handedness and pitch of [5]helicenes via the tether length, inducing significant molecular distortion and affecting chiroptical properties.

Federartiges Verhalten in [8]Helicendiimiden: Wie die Ganghöhe die optische Anisotropie und die elektronische Konjugation steuert

Angewandte Chemie, EarlyView.
Die Verbrückung der Stickstoffatome von [8]Helicendiimiden mit verschiedenen Alkylketten ermöglicht präzise Kontrolle der Ganghöhe ihrer Rückgrate. Dies hat tiefgreifende Auswirkungen auf die Molekülpackung, die Chiroptik und die elektronische Konjugation durch den Raum hindurch.

Is a Malleable Active Site Loop the Key to High Substrate Promiscuity? Hybrid, Biocatalytic Route to Structurally Diverse Taxoid Side Chains with Remarkable Dual Stereocontrol

Angewandte Chemie, EarlyView.
A highly stereoselective, dynamic reductive kinetic resolution (DYRKR) entry into myriad Taxotere‐like side chains with Clostridium acetobutylicum alcohol dehydrogenase (CaADH) enzyme is reported. Follow‐on cross couplings expand the structural diversity of the library (36 total examples).
