The development of molecular probes for optical sensing of chiral compounds has received increasing attention in recent years, in particular because of the potential to accelerate asymmetric reaction analysis. In this study, we prepared conformationally f
Chirality Sensing with Stereodynamic Biphenolate Zinc Complexes
Bentley, Keith W.,De Los Santos, Zeus A.,Weiss, Mary J.,Wolf, Christian
, p. 700 - 707 (2015/10/12)
Two bidentate ligands consisting of a fluxional polyarylacetylene framework with terminal phenol groups were synthesized. Reaction with diethylzinc gives stereodynamic complexes that undergo distinct asymmetric transformation of the first kind upon binding of chiral amines and amino alcohols. The substrate-to-ligand chirality imprinting at the zinc coordination sphere results in characteristic circular dichroism signals that can be used for direct enantiomeric excess (ee) analysis. This chemosensing approach bears potential for high-throughput ee screening with small sample amounts and reduced solvent waste compared to traditional high-performance liquid chromatography methods.
