Sensing the chirality of various organic solvents by helically arranged π-blades†
Abstract
Although the chiral enrichment of dynamic prochiral molecules usually requires a strong interaction with a chiral source, the enantiomer ratio of a propeller-shaped molecule, obtained by a recently developed boron-mediated benzannulation reaction of alkynes, is biased in various organic solvents through solvation for the propeller moieties.
