  摘要：

  The epoxide eudesmanolides 14-21, which constitute epimeric pairs with respect to the configuration of the oxirane ring, have been synthesized in a stereochemically unambiguous way. Comparison of their C-12 NMR spectra with those of the parent olefins 10-13 does not, however, reveal any significant correlation between the configuration of the oxirane ring and the shifts undergone by the signals of the gamma carbon atoms C-1/C-2/C-7/C-9/C-14.
