  Pd(II)-催化对映选择性环收缩用于构建 1,4-苯并恶嗪

  摘要：

  对映选择性环收缩反应尚未被广泛报道。我们开发了 5,6-dihydro-2 H -benzo [ b ][1,4]oxazocines 的对映选择性环收缩，提供对映体富集的 3,4-dihydro-2 H -1,4-benzoxazine衍生物作为单一区域异构体。为了获得具有良好产率和对映体比率（高达 93% 产率，98:2 er）的产品，酸性添加剂是必需的。该反应成功地进行了克级反应，产物易于衍生化。

  Disclosed are a scratch color-developable ink comprising an electron-donating colorless or light-color dye precursor, an electron-accepting color developer and a varnish, wherein a solid particle component contained therein has an average particle diameter of 0.3 to 25 µm, a scratch color-developable ink comprising an electron-donating colorless or light-color dye precursor, an electron-accepting color developer and a varnish, wherein an azaphthalide compound is contained as the electron-donating colorless or light-color dye precursor, and an invisible information printed sheet obtained by printing invisible information on a support with the above scratch color-developable ink. The above scratch color-developable ink makes invisible information visible easily by scratching with a finger nail although the color of an invisible information printed portion is hard to develop by frictional contact during usual handling, gives a high developed color intensity and is free from the occurrence of dust during the visualization of invisible information.

  公开了一种由电子捐献型无色或浅色染料前体、电子接受型显色剂和光油组成的划痕显色墨水，其中包含的固体颗粒成分的平均颗粒直径为 0.3至25微米；一种可刮擦显色油墨，由电子捐赠的无色或浅色染料前体、电子接受的显色剂和光油组成，其中含有作为电子捐赠的无色或浅色染料前体的萘化合物；以及一种通过在支撑物上用上述可刮擦显色油墨印刷隐形信息而获得的隐形信息印刷品。 上述划痕显色油墨虽然在通常的操作过程中通过摩擦接触很难使隐形信息印刷部分显色，但用指甲划痕即可轻松显现隐形信息，显色强度高，而且在显现隐形信息时不会产生灰尘。
