  Synthesis and pharmacological activity of N-hetaryl-3(5)-nitropyridines

  摘要：

  Previously undescribed 2-, 4or 6-substituted hetaryl-3(5)-nitropyridines were synthesized by the interaction of a number of chlorosubstituted 3(5)-nitropyridines with some diazoles or 3-chloropyridazin-6one. In addition, pyrazolyl-3-nitropyridines were prepared by both the above method and cyclization of hydrazinopyridines, which, in turn, were synthesized by the treatment of chlorosubstituted 3-nitropyridines with hydrazine. It has been shown that these compounds have a moderate antibacterial activity against some pathogenic Gram-positive and Gram-negative bacteria (Staphylococcus aureus and Escherichia coli) and a strong protistocidal effect on protozoa species Colpoda steinii surpassing in this respect clinically used reference drugs.

  The synthesis of unprecedented fused azaheterocyclic ring systems is described. Tricycles with either a central pyrazole or a triazole ring were obtained via a nitrene-mediated reaction of nitro bis(hetaryl) derivatives in the presence of triethylphosphite. The cyclization proceeded with complete chemoselectivity for the desired N–N bond formation and was completed within minutes under microwave activation

  can be performed under flow conditions by using inductively heated flow reactors. These include transfer hydrogenations, heterocyclic condensations, pericyclic reactions, organometallic reactions, multicomponent reactions, reductive cyclizations, homogeneous and heterogeneous transition‐metal catalysis. Silica‐coated iron oxide nanoparticles are stable under many chemical conditions and the silica shell
