  描述：

  (E)-N-phenyl-2,3-dimethoxy-1-methylphenanthren-9-imine-imino-d 在 potassium tert-butylate 作用下， 以 N,N-二甲基甲酰胺 为溶剂， 反应 2.0h， 以2%的产率得到(8E,17E,26E)-9,18,27-trideuterio-6,7,15,16,24,25-hexamethoxytriphenanthro<8,9,10-abc:8,9,10-ghi:8,9,10-mno>cyclooctadecene

  名称：

  [abc]-Annelated [18]annulenes

  摘要：

  A 3-fold stereoselective cyclocondensation of the azomethines 3 and 11 yields the [18]annulenes 4 and 12, respectively. The [abc]-annelation of naphthalene or phenanthrene systems realized here for the first time, leads to nonplanar molecules consisting of 'aromatic islands", which are connected by (E)-configured olefinic bridges. The absence of a diamagnetic ring current rules out a macrocyclic aromaticity. The NMR investigation, based on selective deuterations, is sustained by force field calculations (MMX). The disc-like compounds represent discotic mesogens of an enormous diameter. The formation of thermotropic liquid crystals can be achieved by the introduction of long flexible alkoxy chains.
