    Description / Table of Contents: Die relative chemische Verschiebung des OH-Protonen-Signals in den 1H-NMR-Spektren eines Paares diastereomerer ß-Hydroxyether erlaubt eine syn/anti-Zuordnung der relativen Konfiguration. Dies basiert vermutlich auf der Bildung von Strukturen mit intramolekularer Wasserstoff-Brücke. Insofern ist diese Regel auf solche ß-Hydroxyether beschränkt, bei denen nur dieser Typ von intramolekularer H-Brücke ausgebildet werden kann.
    Notes: In a pair of diastereomeric ß-hydroxy ethers the relative 1H-NMR chemical shift of the OH proton is diagnostic for the syn or anti stereostructure. This is probably based on the presence of internally hydrogen-bonded structures. The rule is therefore restricted to those compounds for which only this type of internal hydrogen bonding is accessible.
