  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.

  13-Aryl-substituted tourneforin derivatives were synthesized via the Heck reaction with aryliodides. The structure of (E)-13-(3,4-dimethoxybenzyl)-eudesma-4(5),11(13)-dien-6α,12-olide was confirmed by an XSA. A study of the cytotoxicity of the synthesized derivatives for CEM-13, MT-4, and U-937 tumor models showed promise for the modification.
