Rapid Assembly of the Salvileucalin B Norcaradiene Core [PDF]

, 2010
Preparation of the polycyclic core of the cytotoxic natural product salvileucalin B is described. The key feature of this synthetic strategy is a copper-catalyzed intramolecular arene cyclopropanation to provide the central norcaradiene.

Interplay of Backbone Conformation, Morphology and Thermoelectric Properties of Benzodifuranone‐Isatin Acceptor Polymers

Advanced Electronic Materials, EarlyView.
Modification of polymer backbone via halogenation and comonomer selection leads to conjugated backbones of different stereoelectronic properties, thin film morphologies, and electrical characteristics. The interplay of conformational isomerism, coplanarity, backbone curvature, backbone orientation, and ordering in thin films, electrical conductivity ...

Cooperative Brønsted Acid and Photo‐Promoted Stereoselective Synthesis of Substituted Piperidones

Angewandte Chemie, EarlyView.
A Brønsted acid cooperates with a photoexcited carbonyl triplet to promote stereoselective C─C bond formation in disubstituted piperidones through a chromophore‐activator strategy. The Brønsted acid lowers the excitation energy gap, directs selective C─N bond cleavage over C─C fragmentation after H‐atom transfer, and enables enantioselective C─C bond ...
