Pericyclic reactions of prenylated naphthoquinones: biomimetic syntheses of mollugin and microphyllaquinone

Org Lett. 2005 Dec 22;7(26):5865-8. doi: 10.1021/ol052472u.

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.
