Pyridinium N-2 0-pyridylaminide: synthesis of 3-aryl-2-aminopyridines through an intramolecular radical process
نویسندگان
چکیده
Tris(trimethylsilyl)silane (TTMSS) and azobisisobutironitrile (AIBN) promote the intramolecular heteroarylation of arenesulfonamides with pyridyl radicals under thermal conditions. The arenesulfonamides are easily prepared from pyridinium N-2 0pyridylaminide. The heteroarylation process involves pyridyl radical cyclization and ipso substitution. q 2004 Elsevier Ltd.

Two isomeric 3 0,5 0diaryl pyridinium N-(2 0-azinyl)aminides were also prepared. 2006 Elsevier Ltd. All rights reserved. Functionalization of heterocycles through...
متن کاملBenign synthesis of N-aryl-3,10-dihydroacridin-1(2H)-one derivatives via ZnO nanoparticle-catalyzed Knoevenagel condensation/intramolecular enamination reaction
An efficient construction of 2-(N-arylamino)benzaldehydes and N-aryl-3,10-dihydroacridin-1(2H)-one derivatives starting from 2- hydroxybenzaldehydes has been developed. The synthesis of N-aryl-3,10-dihydroacridin-1(2H)-ones is based on the Knoevenagel condensation of dimedone to various 2-(N-arylamino)benzaldehydes, followed by an intramolecular enamination in the presence of 20 mol% of nanocry...

Abstarct:A simple one-pot synthesis of pyrano[ 2,3-c]pyrazoles was developed by a three-component reaction of various benzaldehydes, malononitrile and 1-phenyl or hydro-3-methyl-1H-pyrazol-5(4H)-one in the presence of N-methyl pyridinium p-toluene sulfonate (NMPyTs) as a catalyst. All of the synthesized compounds were identified by IR, 1H NMR, 13C NMR and mass spectroscopy techniques. In the me...
متن کاملMechanistic studies on the CAN-mediated intramolecular cyclization of δ-aryl-β-dicarbonyl compounds
The synthesis of 2-tetralones through the cyclization of δ-aryl-β-dicarbonyl substrates by using CAN is described. Appropriately functionalized aromatic substrates undergo intramolecular cyclizations generating 2-tetralone derivatives in moderate to good yields. DFT computational studies indicate that successful formation of 2-tetralones from δ-aryl-β-dicarbonyl radicals is dependent on the sta...
