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
