Photoelektrochemische Eisen(III)‐Katalyse für C─H‐Fluoralkylierungen im synthetischen Spätstadium

Angewandte Chemie, EarlyView.
Eine effiziente elektrophotochemische C─H‐Fluoralkylierung von komplexen bioaktiven Verbindungen mit verfügbaren Fluoralkylcarbonsäuren unter Verwendung eines günstigen Eisen(III)‐Katalysators begleitet von der Wasserstoffentwicklungsreaktion wurde entwickelt.

Titan‐vermittelte Umlagerung von Bis(alkinyl)boranen: B–C‐Aktivierung vs. C–H‐Aktivierung

Angewandte Chemie, EarlyView.
Bis(alkinyl)borane mit verschiedenen B‐Substituenten reagierten mit Cp*2Ti(Me3SiCCSiMe3), was zur Bildung von B–C‐Aktivierungsprodukten (oben rechts) bzw. C–H‐Aktivierungsprodukten (unten rechts) führte. Kurzzusammenfassung Es wurden Reaktionen zwischen Rosenthal‐Titanocen‐ (Cp2Ti) und Decamethyltitanocen‐ (Cp*2Ti) Synthonen mit verschiedenen Bis ...

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

Phosphinoisocyanide/Alkyne Cycloaddition: Generation of Azaphospholylidene (NPHC) Ligands

Angewandte Chemie, EarlyView.
Rare examples of nitrogen phosphorus heterocyclic carbene (NPHC) complexes of group 6 and 7 metals arise from a facile [3 + 2] cycloaddition of phosphinoisocyanides (LnM‐CNPR2) with activated alkynes. The NPHC ligands are shown to be comparatively π‐acidic and the group 6 examples undergo facile transfer of the intact carbene to gold(I) centres ...

Site‐Selective Carbonylation of Azetidines via Copper‐Catalyzed Difluorocarbene Insertion

Angewandte Chemie, EarlyView.
We disclose a site‐selective Cu‐catalyzed carbonylation of azetidines promoted by difluorocarbene insertion at low temperature, enabling access to a variety of functionalized γ‐lactams and a therapeutic agent for diabetes (40 examples). This skeletal expansion strategy provides a distinct disconnection approach to synthesize medicinally relevant five ...
