Enantioselective Desymmetrization of Meso Bicyclic Hydrazines: A Novel Approach to the Asymmetric Synthesis of Polysubstituted Amino Cyclopentanic Cores
摘要:
Catalytic asymmetric hydroboration can be successfully applied to meso bicyclic hydrazines. The resulting alcohols are of great synthetic interest and can lead in a straightforward manner to cyclopentanic diamino alcohols with good enantiomeric purity.

The supramolecular chiral recognition between rac-2a and several structured RNA leads to a distinct (19)F NMR signal splitting. The (19)F NMR analysis of the diastereomeric pairs formed upon binding of this racemic probe delivers a topological footprint of the RNA. This phenomenon can be exploited to investigate dynamic events involving structural equilibria, as demonstrated in a melting experiment
