  Structure and chemistry of some ophiobolin D derivatives.

  摘要：

  Two different types of transannular reactions occurred in the eight-membered rings of ophiobolin D derivatives during decarboxylation and mild base treatment of the decarboxylated product. Possible reaction mechanisms, together with the chemical and spectral properties of these compounds, are presented on the basis of the configuration and conformation of two key compounds determined by X-ray crystallographic analyses.
