Manganese‐Catalyzed Enantioselective Dearomative Epoxidation of Naphthalenes with Aqueous Hydrogen Peroxide

Angewandte Chemie, EarlyView.
The enantioselective epoxidation of naphthalenes into their corresponding arene oxides with aqueous hydrogen peroxide is described. The reaction combines dearomatization with installation of chemically versatile functionality in an enantioselective manner.

β‐Quaternary α‐Amino Acids via Iridium‐Catalyzed Branched and Enantioselective Hydroalkylation of 1,1‐Disubstituted Styrenes

Angewandte Chemie, EarlyView.
A cationic Ir(I)‐complex modified with the chiral diphosphine DM‐SEGPHOS mediates the enantioselective hydroalkylation of diverse α‐substituted styrenes with N‐aryl glycine derivatives. The products are readily advanced to β‐quaternary α‐amino acids that are inaccessible or cumbersome to access by other means. Abstract A cationic Ir(I)‐complex modified

closo‐Carboranylanaloga von β‐Arylethylaminen: Direkte Synthese aus Alkenen mittels EnT‐Katalyse

Angewandte Chemie, EarlyView.
Eine Strategie zur direkten Synthese von closo‐Carboranylanaloga medizinisch relevanter β‐Arylethylamine aus Alkenen wird vorgestellt. Die Reaktion basiert auf der erstmaligen Erzeugung von closo‐Carboranylradikalen mittels Energietransfer‐(EnT)‐Katalyse und ihren besonderen mechanistischen Merkmalen.

Supramolecular Recognition of a DNA Four‐Way Junction by an M2L4 Metallo‐Cage, Inspired by a Simulation‐Guided Design Approach

Angewandte Chemie, EarlyView.
DNA Holliday junctions, or four‐way junctions (4WJs) are an attractive therapeutic target due to their prevalence in DNA replication and repair, and viral disease. Combining experimental and computational methods, we show that quadruple‐stranded dinuclear platinum metallo‐cages are an excellent size and shape match for the cavity of the 4WJ open ...

Ruthenium‐Katalysierte ortho‐Arylierung von Benzoesäuren mit Arylthianthreniumsalzen

Angewandte Chemie, EarlyView.
Es wurde eine katalytische Ortho‐Arylierungsmethode entwickelt, mit der Arylthianthreniumsalze in Carboxylat‐funktionalisierte Biaryle umgewandelt werden können. Die Carboxylatgruppe kann in situ entfernt oder für eine weitere Derivatisierung verwendet werden.
