  A Modular Synthesis of Unsymmetrical Tetraarylazadipyrromethenes

  摘要：

  A stepwise route to unsymmetrical tetraarylazadipyrromethenes by a condensation of 2,4-diaryl-5-nitroso-pyrroles with 2,4-diarylpyrroles is described. This modular building-block approach allows for the introduction of up to four different aryl substituents on the azadipyrromethene and is tolerant of a varied substituent set. An efficient synthesis of the 2,4-diarylpyrroles building blocks from 1,3-diaryl-4-nitro-butan-1-ones by nitro hydrolysis to a keto-aldehyde and subsequent ammonia condensation reaction has been achieved. The facile conversion of 2,4-diarylpyrroles into their alpha-nitroso analogues by their reaction with sodium nitrite generated the second building block required for the synthesis.

  processes. Certain pyrrole derivatives are fluorescent and may be used as molecular probes or biomarkers in the diagnosis of diseases, such as Alzheimer’s or Parkinson’s. Herein is reported the synthesis of five new pyrrole derivatives bearing phenyl rings on positions 1, 2, and 4, with electron-donating groups at the periphery. The introduction of more or stronger electron-donating groups red-shifts and
