Isothiourea‐Catalysed Acylative Kinetic and Dynamic Kinetic Resolution of Planar Chiral Paracyclophanols

Angewandte Chemie, EarlyView.
The highly selective acylative (dynamic) kinetic resolution of racemic paracyclophanols catalysed by a chiral isothiourea (5 mol%) is described (up to s = 50 at 49% conversion or up to 98:2 er and 96% yield in 30 examples). Rotational barriers were analysed for paracyclophanols and selected ester products.

Asymmetric Aziridination of Allylic Carbamates Using Ion‐Paired Rhodium Complexes and Extrapolation to C─H Amination of Phenethyl Carbamates

Angewandte Chemie, EarlyView.
Aziridination of alkenes is an important route to chiral nitrogen‐containing building blocks. We report that carbamate‐functionalized allylic alcohols undergo highly enantioselective aziridination using achiral dimeric Rh complexes ion‐paired with cinchona alkaloid‐derived chiral cations.

Hochgradig enantioselektive Organokatalyse mit zweizähnigen Halogenbrückendonoren

Angewandte Chemie, EarlyView.
In einer Mukaiyama‐Aldol‐Modellreaktion mit allgemeinen Substraten wurden hohe Enantioselektivitäten mit einem modifizierbaren, bidentaten Iod(I)‐basierten Halogenbrücken‐Organokatalysator erreicht. Die entscheidende Rolle der Halogenbrücken wurde durch das schlechte Abschneiden des entsprechenden Wasserstoffbrückendonors und durch DFT‐Berechnungen ...

Shaping of a Reactive Manganese Catalyst Enables Access to Polyfunctionalized Cyclohexanes via Enantioselective C(sp3)─H Bond Oxidation of 1,3‐meso Diethers

Angewandte Chemie, EarlyView.
Structural shaping of a highly reactive chiral Mn‐oxo species translates into exceptionally enantioselective C─H oxidation catalyst of cyclohexyl 1,3‐meso diethers (up to >99% ee) leading to polyfunctionalized cyclohexanes. Abstract Chiral polyoxygenated cyclohexanes are valuable constituents of biologically relevant products.
