✦ Synopsis

Sterically hindered a-glycols, obtained from electrochemical hydrodimenhation of polycyclic ketones (idanone, tetralone, chromanone, flavanone, xanthone and fluorenone), were studied by 'H and -C NMR. Evidence of conformational hindrance was deduced from the 'H spectra; meso or racemic configurations and the conformational stereochemistry of these molecules in solution were assigned.
