The picture is taken from the well-known scenic spot - Huangguoshu waterfall in Guizhou Province, China. The inset picture describes chiral secondary amine catalyzed asymmetric cascade Michael-aldol-dehydration reactions, developed by Wang and co-workers. These powerful cascade processes afford efficient approaches to one-pot construction of complex benzo(thio)pyrans and hydroquinolines from simple achiral substances.

The cover shows the 13C NMR traces of enantioenriched propargylic fluorides in the chiral liquid crystalline solvent poly(y-benzylL-glutamate) (PBLG) and chloroform. The data revealed that the electrophilic anti SE2' fluorination of allenylsilanes proceeds with highly efficient transfer of chirality.

Both enantiomers of 2-amino-1-phenylethanol (2-APE) were resolved by the use of dehydroabietic acid (DAA), a natural chiral acid, by switching resolving solvents. The crystal structures of both diastereomeric salts, (R)-APE/DAA and (S)-APE/DAA, showed that EtOH molecule was only involved in (R)-APE/DAA to complete the necessary H-bond network.

Not much fits in between sheets of graphite, but there's enough room to accommodate nanometer clusters of nickel. And with reaction partners in the surrounding solution ready to couple as the sheets slide and eventually expose the metal, heterogeneous catalysis can occur to make either C-C or C-H bonds.
