(4S,5S,6S)-4-Hy­droxy-3-meth­oxy-5-methyl-5,6-ep­oxy­cyclo­hex-2-en-1-one

The title compound, C8H10O4, was isolated from culture extracts of the endophytic fungus Xylaria sp. (PB-30). The cyclo­hexenone ring exhibits a flattened boat conformation. In the crystal structure, mol­ecules related by translation along the b axis are linked into chains through O—H⋯O hydrogen bonds. Weak non-classical C—H⋯O contacts are also observed in the structure
