  Dimethoxy[n.2]metacyclophanes 9 (n=2, 3, 4, 5, and 6) and 10 were stereoselectively obtained in 61 – 87% yields by means of[2+2] photocycloaddition. Their conformations, when n=3-6, are exclusive of syn, while the dimethoxy[2.2]metacyclophane exists as a mixture of syn and anti isomers with the ratio of 4:3. After their Birch reduction, [n.4]metacyclophanes 11 (n=2 - 6) were successfully obtained in

  通过[2 + 2]光环加成法以61 – 87％的产率立体选择性地获得了二甲氧基[n.2]甲基环环烷9（n = 2、3、4、5和6）和10。当n ＝ 3-6时，它们的构象不包括顺式，而二甲氧基[2.2]间环phane以顺式和反式异构体的比例为4：3的混合物形式存在。减少桦木含量后，成功地以59 – 94％的收率获得了[n.4]个亚甲基环烷11（n = 2-6）。当n ＝ 2-4为反或n ＝ 5且6为syn时，它们的构象。二羟基[n.4]甲基环已烷16（n = 2-6）和二羟基[n.2]甲基环已烷17（n = 4、5和6）的收率分别为93-100 ％和78-95 ％甲氧基脱甲基后。的构象图16和17与相应的二甲氧基甲基环环烷相同。与单体酚一样，16和17中酚基的酸度较低。在通过三氟甲磺酸酯18进行烯化和乙烯基化后，在25 ℃下，亚环烷19和21分别立体选择性地得到三桥[n.2.2]（1,3,4）环烷20和22立体产率为65

  Provided is a liquid crystal display element that can be baked at a low temperature when forming a liquid crystal alignment film capable of imparting an alignment regulating property and a pretilt angle developing property via a photoalignment method. Further provided is a liquid crystal display element in which the liquid crystal pretilt angles are highly stable, and display burn-in hardly occurs even due to long usage. Further provided are a vertical liquid crystal alignment film to be used in the liquid crystal display element, and a liquid crystal aligning agent with which it is possible to provide the vertical liquid crystal alignment film. A liquid crystal aligning agent of the present invention contains: component (A), which is a polymer including (A-1) a site having an isocyanate group and/or a blocked isocyanate group and (A-2) a site having photoreactivity; component (B), which is a compound having, in a molecule, at least two functional groups of at least one type selected from the group consisting of an amino group and a hydroxyl group; and an organic solvent.
