The 13C and 1H NMR spectra of α-methylidene-β-hydroxy-γ-alkoxy-pentanoates and -decanoates are presented. These data are consistent with a preferred conformation in which an intramolecular hydrogen bond is present. Very characteristic steric shifts in the 13C and 1H NMR spectra provide an efficient tool for the configurational assignment for this class of compounds.

Abstract

The 13C and 1H NMR spectra of α-methylidene-β-hydroxy-γ-alkoxy-pentanoates and -decanoates are presented. These data are consistent with a preferred conformation in which an intramolecular hydrogen bond is present. Very characteristic steric shifts in the 13C and 1H NMR spectra provide an efficient tool for the configurational assignment for this class of compounds.
