title: A simple determination method of the absolute configuration of 1-arylethanthiols by an intramolecular CH/pi shielding effect in 1H-NMR of diastereomeric thiol esters.
abstract: A simple method for the determination of the absolute configuration of 1-arylethanthiols was achieved by the observation of an intramolecular CH/pi shielding effect in (1)H-NMR of the corresponding thiol esters. (S)-Isomer of the diastereomers always shows remarkable shielding effect.
