Abstract
The title compounds, (2R,2''S,3b'S,4a'R,7b'S,8a'R)-perhydrodispiro[furan-2,3'-dicyclopenta[a,e]pentalene-7',2''-furan]-5,5''-dione, C20H26O4, and (3aR,3bR,4aR,4bS,5aS,8aR,8bR,9aR,9bS,10aS)-perhydrodipentaleno[2,1-a:2',1'-e]pentalene-1,6-dione, C20H26O2, are intermediates identified during the synthesis of dodecahedrane. Crystallographic studies have established the ring-junction stereochemistry for these important intermediates. All the ring junctions are cis-fused, and the molecular packing is stabilized by van der Waals interactions.
