Abstract

original image

Die transannulare Cyclisierung von Dehydrobenzoannulenen ist eine leistungsfähige Methode zum Aufbau neuer Kohlenstoffgerüste, die auf andere Weise nur schwer zugänglich sind. In ihrer Zuschrift auf S. 4278 ff. zeigen Y. Tobe und Mitarbeiter, dass die Reaktion von Dehydrobenzo[14]annulenen mit n-Butyllithium über eine dreifache transannulare Bindungsbildung in einem 14-gliedrigen Ring zu einer ungewöhnlichen oxidativen Cyclodimerisierung unter Bildung achtgliedriger Ringe führt.
