|Synthesis and characterization of novel chiral derivatizing agents containing β-keto-anthracene adducts (KAAs) by <sup>1</sup>H-NMR: Aromatic influence and chiral alcohol absolute configuration determination
|Biochemistry, Genetics and Molecular Biology;Chemistry
|© 2019 The Royal Society of Chemistry. New alternative chiral derivatizing agents, β-keto-anthracene adducts (KAAs), were accomplished and the influence of aromatic moieties at the α-carbon position for elucidation of the absolute configuration of chiral secondary alcohols via NMR was studied. The α-benzoyl substituted KAAs strongly enhance the anisotropic effect which produced greater ΔδRS values than other conventional reagents. We propose a simplified model to describe the conformations and to assign the absolute configuration in several chiral alcohol samples.
