  描述：

  2,3,6,7-Tetramethylene-1,4,5,8-tetrahydronaphthalene 在 potassium tert-butylate 作用下， 以 二氯甲烷 为溶剂， 反应 49.0h， 生成 Tetraethyl 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16-hexadecahydrohexacene-2,3,10,11-tetracarboxylate
  参考文献：
  名称：

  Molecular ladders constituted of laterally-fused 1,4-cyclohexadiene subunits. Open-chain models of the [n]beltenes.

  摘要：

  A practical synthesis of 2,3,6,7-tetramethylene-1,4,5,8-tetrahydronaphthalene (11) has opened up several avenues for the elaboration of molecules consisting largely or exclusively of 1,2:4,5-fused 1,4-cyclohexadiene subunits. Diels-Alder addition of dienophiles to both 1,3-diene segments of this reactive hydrocarbon leads directly to 1,4,5,6,7,10,11,12-octahydrotetracene and substituted derivatives of this polyolefin. A route to the hexacene homolog is available by twofold [4 + 2] cycloaddition of a benzyne followed by Birch reduction. For reasons of solubility, the benzyne should carry alkyl groups in its 4- and 5-positions. Finally, a two-step cyclohomologation scheme is described that allows for the systematic controlled extension of the structural features present in 11 to its tetra- and hexacyclic congeners. The insolubility of the latter hydrocarbon limits its further exploitation in synthesis.
