| Zusammenfassung: | The crystal structure of the title compound, (−)‐(4R,5R,4′′R,5′′R)‐4,5,4′′,5′′‐tetramethyldispiro[1,3‐dioxalane‐2,1′(2′H)‐acenaphthylene‐2′,2′′‐1,3‐dioxalane], C20H22O4, contains molecules separated by normal van der Waals distances. The dioxacyclopentane rings adopt envelope conformations and the naphthalene moiety is essentially planar while the two C atoms bonded to it lie 0.122 (8) and 0.105 (8) Å on opposite sides from its mean plane. |
