A very efficient and simple route to bicyclic ketones using Propargylic silanes is described. The cyclization is initiated by a trace of Amberlyst 15 that is added to a reaction vessel. Stirring at room temperature and non-aqueous work-up yielded several bicyclic ketones in high chemical yields containing the synthetically very useful allene.
