Quantitative chirality sensing of amines and amino alcohols via Schiff base formation with a stereodynamic UV/CD probe.

A stereodynamic chemosensor that can be used for simultaneous determination of the absolute configuration, enantiomeric composition and total concentration of chiral amines and amino alcohols based on two fast optical measurements was prepared and tested. The free sensor is CD-silent and produces characteristic blue-shifted UV and CD signals upon substrate binding via Schiff base formation. The potential in high-throughput screening applications and for rational sensor developments are discussed.
