摘要：

Norbornene derivatives 4 and 5 containing sidechains bearing an internal alkyne and either a terminal alkene or a terminal alkyne were found to undergo a cascade of metathesis reactions when treated with ruthenium based metathesis catalysts to form highly functionalised pentacyclic products. The reactions illustrate an interesting difference in reactivity between Grubbs' catalyst and the second generation catalyst, with the former being more reactive for the early steps of the cascade.
