Structural Basis for the Catalytic Mechanism of ATP‐Dependent Diazotase CmaA6

Angewandte Chemie, EarlyView.
Several diazotases have been reported in recent years, but the detailed catalytic mechanism is unclear. From X‐ray crystallography and Cryo‐EM analysis, we obtained the structure of a diazotase CmaA6, which synthesizes 3‐diazocoumaric acid. Kinetic analysis and computational analysis indicated that CmaA6 catalyzes diazotization via an unprecedented ...

Azuperylene: The Nonalternant Isomer of Perylene

Angewandte Chemie, EarlyView.
As a nonalternating isomer of perylene, azuperylene (AP) is formed by the C─H/C─I coupling reactions we developed at the 1,8‐positions of azulene. The aromatic characteristics of the initial azulene are retained, and side chain modifications regulate the stacking pattern. The core of AP has smaller mutual perturbation compared to perylene.

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.

Stable Mg2+ Dication Weakly Stabilized/Coordinated in Solution: Synthesis, Structure, Reactivity, and Use in Catalysis

Angewandte Chemie, EarlyView.
Stable Mg2+ dication stabilized only by weakly coordinating carborates was first prepared and structurally characterized as a soluble salt in organic solvents. Combined experimental and theoretical data provided valuable insights into its behavior/reactivity in solution.

Cooperative Photometallobiocatalysis: Nonheme Fe Enzyme‐Catalyzed Enantioconvergent Radical Decarboxylative Azidation, Thiocyanation, and Isocyanation of Redox‐Active Esters

Angewandte Chemie, EarlyView.
Through the directed evolution of an underexploited nonheme Fe extradiol dioxygenase, we developed a unified cooperative photobiocatalytic strategy to allow for three types of enantioconvergent radical transformations, including azidation, thiocyanation, and isocyanation.
