  Selective Sequential Cross-Coupling Reactions on Imidazole towards Neurodazine and Analogues

  摘要：

  Polysubstituted imidazoles represent a common structural motif in bioactive molecules. A modular and flexible strategy towards 2,4,5-triarylated imidazoles is reported applying a Suzuki-Miyaura cross-coupling protocol. Employing 1-protected 2,4,5-tribromoimidazole as starting material, both stepwise and one-pot protocols towards the title compounds are disclosed. The utility of the approach was demonstrated by synthesizing neurodazine, a biologically active molecule affecting neuronal cell differentiation.

  A series of 4-(piperidin-4-yl)-1-hydroxypyrazole (4-PHP) 3- or 5-imidazolyl substituted analogues have been designed, synthesized, and characterized pharmacologically. All analogues showed binding affinities in the low micro- to low nanomolar range at native rat GABAA receptors and were found to be antagonists at the human α1β2γ2s receptor. The structure–activity relationship of the compound series

  已经设计，合成和表征了一系列4-（哌啶-4-基）-1-羟基吡唑（4-PHP）3-或5-咪唑基取代的类似物。所有的类似物表现出结合亲和力的低微以低纳摩尔范围在天然大鼠GABA甲受体和被认为是在人α拮抗剂1 β 2 γ 2S受体。该化合物系列的结构-活性关系表明，在正构结合位点4-PHP支架附近，先前发现的腔在大小和结构上存在明显差异。

  o-Chlorohetarenecarbaldehydes react with sodium azide at low temperature yielding moderately stable o-azidohetarenecarbaldehydes. With hydrogen sulfide these compounds are reduced to the corresponding stable o-amino aldehydes. Both reaction steps give high yields.
