The reductive ring-opening of hydroperoxides derivedfrom cyclic ketones leads to alkyl radicals which can effectively be trapped by arenediazonium salts. This synthetic transformation yielding azo carboxylic acids or lactams, after a reductive step, can be classified as a radical version of the well-known Beckmann rearrangement. In this article, we present results on the scope, the limitations and

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.
