Flavin Catalysts in Organic Synthesis

Angewandte Chemie, EarlyView.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Ruthenium(II)-imine pincer complexes for sustainable synthesis of amides via hydration of nitrile with low catalyst loading and sub-stoichiometric amount of base

Results in Chemistry
Two new ruthenium(II) complexes with triphenylphosphine and tridentate benzimidazole-based ligands were synthesized and structurally characterized. The complexes were tested as homogenous catalysts for the hydration of nitriles to amides under mild and ...

Broad‐Spectrum, Cell Envelope‐Active Marinocyclin Antibiotics From a Coral‐Derived Bacterium Are Effective Against Colistin‐Resistant Bacteria

Angewandte Chemie, EarlyView.
Marinocyclins, polycationic macrocyclic depsipeptides, were discovered by genome mining from the marine coral‐derived bacterium Aquimarina megaterium. The compounds have broad‐spectrum activity against gram‐positive and gram‐negative ESKAPE bacteria.
