A route to simpler analogues to bioactive puupehedione derivatives involving a hetero Diels–Alder cycloaddition of a o-quinonemethide is described. These intermediate species are generated via fluoride-induced desilylation of silyl derivatives of o-hydroxybenzyl iodides. Remarkable short reaction times and very mild experimental conditions are the main features of this method.
