A new, simple and short route to 2-(6-methoxycarbonylhexyl)-cyclopent-2-en-1-one(overall yield: 33%) starting from ethyl-10-undecenoate is reported. The main feature of this synthesis is a new cobalt-catalyzed carbonylation of the intermediate epoxide, which occurs with satisfactory yield under very mild conditions.
