Acid-catalyzed ring-opening cyclization of cyclohexane-1,3-dione-2-spirocyclopropanes under metal-free conditions proceeded smoothly at room temperature to provide 2-aryl-3,5,6,7-tetrahydro-1-benzofuran-4(2H)-ones in excellent yields without the formation

An organocatalyzed highly regioselective synthesis of substituted tetrahydrobenzofuran-4-ones based on the ring opening followed by cyclization of epoxides with enamines of 1,3-cyclohexanediones in a domino fashion is described. It is a high yielding (74-93%) synthetic protocol tolerant to a wide range of substrates. Ambient temperature, organocatalytic approach, atom-economy, and formation of water as the only by-product are some of the attractive features of the present methodology.
