Two units of acrylate or methacrylate were connected with 2,4-pentanediol. Michael addition of organometallic compounds to this substrate failed to cause the intended intramolecular Michael addition of the generated enolate, but the addition of carbon radical induced the internal addition to give cyclic compounds in yields up to 79%.
