High relevanceOosporein from Tremella fuciformis.
Tremella fuciformis
Key points
- THE TITLE COMPOUND [SYSTEMATIC NAME: 3,3',6,6'-tetra-hydroxy-4,4'-dimethyl-1,1'-bi(cyclo-hexa-3,6-diene)-2,2',5,5'-tetra-one], C(14)H(10)O(8), was isolated from Tremella fuciformis
- The mol-ecule has 2 symmetry, with the mid-point of the C-C bond linking the cyclo-hexa-dienedione rings located on a twofold rotation axis
- In the mol-ecule, the ring is approximately planar, with an r.m.s. deviation of 0.0093 Å, and the two rings make a dihedral angle of 67.89 (5)°. Inter-molecular O-H⋯O hydrogen bonding occurs in the crystal structure
