title: 3-Hy-droxy-8-oxo-3-nor-methyl-chamigrane-2,7-peroxide.
abstract: In the title compound, C(14)H(22)O(4) (systematic name: 9-hy-droxy-1,5,5-trimethyl-1,8-epidi-oxy-spiro-[5.5]decan-2-one), which was isolated from the fermentation broth of Steccherinum ochraceum, the two six-membered rings adopt chair conformations and are bridged by a peroxide group. The hy-droxy H atom forms a three-centre cyclic inter-molecular O-H⋯(O,O') hydrogen-bonding inter-action with a peroxide and a carbonyl O-atom acceptor, forming [100] chains.
