✦ Synopsis

The '"C and 'H NMR spectra of ar-methylidene-P-hydroxy-y-alkoxy-pentan and -decanoates are presented. These data are consistent with a preferred conformation in which an intramolemlar hydrogen bond is present. Very characteristic steric shifts in the -C and 'H NMR spectra provide an e M e n t tool for the configurational assignment for this class of compounds.
