摘要：

A newly rearranged 2(3-->20)abeotaxane diterpenoid with a unique 6/10/6 skeleton was isolated from the bark of the Chinese yew, Taxus mairei. The structure was established as being 7 beta,13 alpha-diacetoxy-2 alpha,5 alpha,10 beta-trihydroxy-9-keto-2(3-->20)abeotaxane on the basis of 1-D and 2-D NMR data. The relative stereochemistry was defined from the results of a NOESY experiment. This is the first reported isolation of a rearranged 2(3-->20)abeotaxane from Taxus mairei.
