  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.

  developed and employed for the synthesis of 3,4-dihydro-2H-pyrroles via hydrogenation and subsequent cyclization of nitro ketones. The catalyst was identified from a library of 24 heterogeneous catalysts. The key to our hydrogenation/cyclization reaction is the tolerance of aldehydes and ketones as functional groups and the ability to hydrogenate aliphatic nitro compounds efficiently.
