Stereochemical study of hindered α‐glycols by 1H and 13C NMR spectroscopy
View through CrossRef
AbstractSterically hindered α‐glycols, obtained from electrochemical hydrodimerization of polycyclic ketones (indanone, tetralone, chromanone, flavanone, xanthone and fluorenone), were studied by 1H and 13C NMR. Evidence of conformational hindrance was deduced from the 1H spectra; meso or racemic configurations and the conformational stereochemistry of these molecules in solution were assigned.
