  The new and simple ‘LEGO’ system: Its application to the synthesis of superbranched oligopyridines

  摘要：

  The condensation of pyridine-2, 4,6-tricarboxtrisamidrazone 1 with 1,2-dicarbonyl compounds 2 - 3 leads to trisubstituted 1,2,4-triazines 4 - 6. These 1,2,4-triazines can be easily transformed to superbranched pyridines 7 - 9 by [4+2] cycloaddition with norborna-2,5-diene followed by [4+2] cycloreversions of nitrogen and cyclopentadiene. This reaction sequence offers a new, simple and general access to superbranched oligopyridines. (C) 1998 Elsevier Science Ltd. All rights reserved.

• Bis(4-hydroxythiazoles): Novel Functional and Switchable Fluorophores
  作者：Dieter Weiß、Rainer Beckert、Eric Täuscher、Lorena Calderón-Ortiz、Helmar Görls

  A series of 2,2′- and 5,5′-bis(4-hydroxythiazoles) was synthesized according to Hantzsch synthesis. Both phenols and their corresponding anions display a strong fluorescence in the visible spectrum, whereas the emission is shifted bathochromically upon deprotonation. This easy switch makes them suitable for widespread applications, mainly in analysis and supramolecular chemistry. Due to their 1,4-diazadiene substructure, the 2,2′-bithiazoles possess prerequisites for the complexation of metals, however, instead of a copper complex, a dimer which constitutes the 5,5′-C-C coupled product was isolated. In addition, tris(thiazoles) could be constructed.

  根据汉茨合成法合成了一系列 2,2′- 和 5,5′- 双（4-羟基噻唑）。这两种酚类化合物及其相应的阴离子在可见光谱中都显示出强烈的荧光，而在去质子化时，其发射会发生浴色转移。这种易于转换的特性使它们能够广泛应用于分析和超分子化学等领域。由于 2,2′-双噻唑具有 1,4-二氮二烯亚基结构，因此具备了与金属络合的先决条件，但分离出的不是铜络合物，而是构成 5,5′-C-C 偶联产物的二聚体。此外，还可以构建三（噻唑）络合物。
