title: Pericyclic reactions of prenylated naphthoquinones: biomimetic syntheses of mollugin and microphyllaquinone.
abstract: [reaction: see text] A total synthesis of the bioactive naphthohydroquinone mollugin and the related naphthoquinone dimer microphyllaquinone is described. Both syntheses exploit the propensity of prenylated quinones to undergo tautomerization/oxa 6pi-electrocyclizations.
