Notes:
The title compound, C12H16O4, (I), was prepared by oxidation of (5S*,6R*)-1,7-dioxadispiro[4.0.4.4]tetradecane-2,8-diol using silver(I) carbonate and posesses a cis configuration of the two five-membered-ring lactones fused spiro to the six-membered carbocycle, which has a chair conformation. It represents an exceptional structure for bis-tetrahydrofuran units, which are interesting building blocks in natural products. The synthesis, spectroscopic data and X-ray structural analysis are described. The crystal contains discrete molecules separated by normal van der Waals distances.
