A short, formal synthesis is reported for pentalenene. The key steps are copper-catalyzed 1,4-addition of isobutylmagnesium bromide to a cyclooctenone derivative, enolate alkylation with the thiocarbene complex [(@-C5H5)(CO)2Fe=CHSPh]+ PFg-, and cyclopentane ring formation by means of intramolecular
