Update: Enzymatische Synthese für industrielle Anwendungen

Angewandte Chemie, EarlyView.
Die Biokatalyse hat sich zu einer nachhaltigen und wettbewerbsfähigen Alternative zur herkömmlichen chemischen Synthese entwickelt und ermöglicht die enzymbasierte Herstellung nicht nur von chemischen Grundstoffen, sondern auch von (nicht natürlichen) Aminosäuren, (seltenen) Zuckern und synthetischen Nukleotiden.

The Mechanism of Ruthenium‐Catalyzed Directed C─H Arylation of Arenes: The Key Role of Bis‐Cyclometalated Intermediates

Angewandte Chemie, EarlyView.
The mechanism of Ru‐catalyzed N‐directed C─H ortho‐arylation with haloarenes is addressed through experimental stoichiometric, catalytic kinetic, and DFT studies. These reveal a key role for bis‐cyclometallated ruthenium species and show bromoarene activation proceeds via a concerted oxidative addition.

From Amino Acids to α‐Keto Acids via β‐Elimination and Transamination Initiates a Pathway to Prebiotic Reaction Networks

Angewandte Chemie, EarlyView.
A reaction starting from two amino acids, phosphoserine and Gly, reveals a pathway to the α‐keto acid building blocks pyruvate and glyoxylate, key components of a plausible early metabolic system. A one‐pot β‐elimination and transamination sequence also initiates a cascade of protometabolic transformations that provide crucial insights into the ...

A Thorough Characterization of the Tellurocyanate Anion

Angewandte Chemie, EarlyView.
[K@crypt‐222][TeCN] was synthesized from KCN, Te, and crypt‐222 in acetone. We discuss fundamental properties of [TeCN]−: Single crystal X‐ray diffraction, nuclear magnetic resonance (13C, 15N, 125Te), vibrational spectroscopy, and negative ion photoelectron spectroscopy.
