  描述：

  、 乙酰乙酸甲酯 在 (NH₄)2Ce(NO₃)6 or Mn(OAc)3 作用下， 以39.0-40.7的产率得到4-methoxycarbonyl-2-ethynyl-2,5-dimethyl-2,3-dihydrofuran

  μ-[3-4-η-(1-Alken-3-yne)hexacarbonyldicobalt complexes: Radical cyclocondensation mediated by manganese(III) acetate

  摘要：

  A regioselective pathway for the radical reaction of 1-alken-3-ynes with beta-dicarbonyl compounds, mediated by Mn(OAc)3, can be achieved by protection of the substrate triple bond with a hexacarbonyldicobalt moiety. Dihydrofuran and hexahydrobenzofuran derivatives are formed by intermolecular oxidative cyclization of intermediate cobalt-complexed propargyl radicals.
