Gold cyclisiert: Zwei goldkatalysierte oxidative Cyclisierungen von 1,5-Eninen mit 8-Methylchinolin-N-oxid werden vorgestellt (siehe Beispiel). In beiden Reaktionen wird zunächst die Alkinfunktion unter Bildung von α-Carbonyl-Zwischenstufen oxidiert, bevor sich eine intramolekulare Carbocyclisierung anschließt.
