  通过焓控制的亲核官能化对嘧啶进行 C2 选择性、官能团发散胺化

  摘要：

  杂芳胺的合成因其在小分子发现中的重要性而一直是有机化学中的一个重要课题。特别是，2-氨基嘧啶代表了一种在生物活性分子中普遍存在的高度特权结构基序，但通过直接功能化引入嘧啶 C2-N 键的一般策略是难以捉摸的。在这里，我们描述了一种用于位点选择性 C-H 官能化的合成平台，该平台提供嘧啶基亚胺盐中间体，然后可以原位转化为各种胺产物。基于机制的试剂设计允许嘧啶的 C2 选择性胺化，开辟了位点选择性杂芳基 C-H 官能化的新范围。

  Synthesis and Photophysical Investigation of a Series of Push–Pull Arylvinyldiazine Chromophores

  摘要：

  A new series of push-pull arylvinyldiazines has been efficiently prepared by aldol condensation between the appropriate methyldiazine and aromatic aldehyde. The optical absorption and emission properties of these chromophores were studied in different solvents and media. These compounds act as polarity sensors with a strong positive emission solvatochromism. This behavior suggests a highly polar emitting state, which is characteristic of compounds that undergo an internal charge transfer upon excitation. These molecules also exhibit halochromic properties and are potential colorimetric and luminescence pH sensors. The second-order nonlinear properties have been investigated for some of the compounds, and large and positive mu beta are obtained, in particular, for pyrimidine derivatives.

• C2-Selective, Functional-Group-Divergent Amination of Pyrimidines by Enthalpy-Controlled Nucleophilic Functionalization

  Synthesis of heteroaryl amines has been an important topic in organic chemistry because of their importance in small-molecule discovery. In particular, 2-aminopyrimidines represent a highly privileged structural motif that is prevalent in bioactive molecules, but a general strategy to introduce the pyrimidine C2–N bonds via direct functionalization is elusive. Here we describe a synthetic platform
