The title compound, C~22~H~28~O~8~, was prepared from the natural diterpenoid macrocalyxin J by two steps. It is built up from five fused rings: three six-membered rings and two five-membered rings. Two molecules are present in the asymmetric unit; both independent molecules have the same absolute c
The title compound, C~38~H~50~O~6~, also known as guttiferone A, was isolated from the medicinal plant __Symphonia globulifera__. It is a benzophenone derivative where one aryl group is derivatized to give a bicyclic system which has two prenyl groups attached to the bridgehead. One of the cyclohexa
