Supramolecular-Directed Chiral Induction in Biaryl Derivatives
摘要:
A thermodynamically controlled resolution has allowed for the generation of diastereomerically enriched complexes, by chirality transfer from ail enantiopure building block to a dynamically racemic biaryl derivative. A switchable sense of induction could be achieved depending on the substituents of the chiral block.

A general catalytic method for asymmetric C-alkylation of nitroalkanes using nickel catalysis is described. This method enables the formation of highly enantioenriched β-nitroamides from readily available α-bromoamides using mild reaction conditions that are compatible with a wide range of functional groups. When combined with subsequent reactions, this method allows access to highly enantioenriched
