The molecule is an octahydronaphthalene that is stemphyloxin I in which the C=C bond of the enol moiety has been reduced to a C-C bond. It has a role as a fungal metabolite. It is an alpha-hydroxy ketone, a beta-hydroxy ketone, a diketone, a cyclic ketone, a member of octahydronaphthalenes, a primary alcohol, a tertiary alcohol and a tetrol. It derives from a stemphyloxin I.
