Wasabidienones B0 and B1 were isolated from Phoma wasabiae Yokogi, a fungus causing widespread destruction of rape, cabbage and wasabi. The o-quinol framework is rather unusual in nature, since most of these compounds readily undergo Diels-Alder dimerization. The focal step of this synthesis is an oxidative dearomatization of the phenol F using SIBX, a commercial, stabilized, non-explosive form of IBX as the oxidant.
