Two short and simple synthetic routes to the prostaglandin synthons 2-(6-carboxyhexyl)- and 2-(6-methoxycarbonylhexyl)cyclopent-2-en-1-one have been developed. The first is based on a cyclohexanone oxidative transformation with hydrogen peroxide and di-tert-butyl peroxide, the second on the free radical addition reaction of methyl 9-oxononanoate to acrylaldehyde diacylal.

A new, simple and short route to 2-(6-methoxycarbonylhexyl)-cyclopent-2-en-1-one (overall yield:33percent) 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.
