  Efficient macrocyclization using methylene-tethered terminal dienes and bis(manganese(III)-enolate)s

  摘要：

  Macrocyclic compounds, which have two fused dihydrofuran rings, were synthesized with complete control by the oxidation of alpha,alpha,omega,omega-tetraaryl-alpha(omega-1)-alkadienes 1(x) with manganese(III)-oligomethylenebis(enolate) complexes directly formed by the reaction of the ohgomethylene bis(3-oxobutanoate)s 2(y) with manganese(III) acetate in situ The oxamethylene-tethered macrodiolides 5 and 7 were also produced in good to moderate yields by a similar oxidation The key intermediate, an election donor-acceptor-like complex, was proposed for the efficient macrocyclization reaction (C) 2010 Elsevier Ltd.
