47_26/2008Cover Picture: PdII-Catalyzed Enantioselective Activation of C(sp2)-H and C(sp3)-H Bonds Using Monoprotected Amino Acids as Chiral Ligands (Angew. Chem. Int. Ed. 26/2008)

Gearing between the α carbon atom and the nitrogen atom of an amino acid relays chiral information to the palladium(II) center, which cleaves C-H bonds asymmetrically. In their Communication on page 4882 ff., J.-Q. Yu et al. report on the palladium(II)-catalyzed enantioselective alkylation of sp2 and sp3 C-H bonds with boronic acids.

Hydrogen Abstraction and Electron Transferfor001

Aminoxyl radicals can participate in a chemical reaction in two ways: by hydrogen atom transfer (HAT) or by electron-transfer (ET). The preferred mechanism depends on the substrate and the redox potential of the radicals, as C. Galli et al. explain in their Minireview on page 4790 ff.


Open-Framework Structuresfor002

A huge variety of compounds with open-framework structures can be prepared through the use of different inorganic oxo anions. The syntheses and properties of these structures are described by S. Natarajan and S. Mandal in their Review on page 4798 ff.


Nanoconjugate Drug Delivery Vehiclesfor003

Drug release can be controlled when the active compound is integrated into a polymer nanoparticle, as J. Cheng and R. Tong show in their Communication on page 4830 ff.
