  A facile synthesis of 3,5-halo and aryl 1H-pyridin-2-ones from pyridinium N-(pyridin-2-yl)aminide

  摘要：

  The synthesis of halogenated and arylated 1H-pyridin-2-ones starting from pyridinium N-(pyridin-2-yl)aminides is described. The synthetic pathway involves the reaction of pyridinium N-(5-bromopyridin-2-yl)aminide, N-(3-bromo-5-chloropyridin-2-yl)aminide or N-(3,5-dibromopyridin-2-yl)aminide with different boronic acids to afford monosubstituted and disubstituted aminides in good yields. An additional bromination in the 3-position of N-(5-arylpyridin-2-yl)aminides was performed. Finally, reduction of the N-N bond followed by the reaction of the corresponding 2-aminopyridines with sodium nitrite/sulfuric acid in water yields 3,5-disubstituted 1H-pyridin-2-ones in good yields.

  Suzuki reaction on pyridinium N-haloheteroarylaminides: regioselective synthesis of 3,5-disubstituted 2-aminopyrazines

  摘要：

  An extensive study of Suzuki-Miyaura cross-coupling processes on N-pyridinium bromoazinyl aminides has been performed. Mono- and disubstitution on 5- and 3,5-bromo derivatives produced the corresponding aryl derivatives. In the disubstituted compounds regioselective substitution at the 3-position occurred, vicinal to the aminide nitrogen, and this was more evident in pyrazine derivatives. The commonly used strategy involving N-alkylation and reduction of the N-N bond gave rise to a series of 2-alkylamino-3,5-disubstituted-pyrazines. (c) 2007 Elsevier Ltd. All rights reserved.

  Differently modified 2-aminopyridines and pyrazines bearing an arylazo group at the 3- or 5-position have been generated from pyridinium N-aminides in a regioselective fashion. The detailed chemistry starts with attack of the N-aminide on a diazonium salt, to form the arylazo derivative. N-alkylation on the exocyclic nitrogen and reduction to break the N–N bond then affords the final compounds, as

  The synthesis of dipyridopyrazole and pyridopyrazolopyrazine derivatives--both of which incorporate a 3-aryl moiety--can be achieved in moderate yields by intramolecular radical arylation of pyridinium N-aminides using tris(trimethylsilyl)silane and azobisisobutyronitrile. Improved results were obtained on using Pd direct arylation in conjunction with microwave irradiation. A preliminary study into the fluorescent properties of the target compounds is also reported.

  The synthesis of a set of new N-heteroarylpolyamines is reported. A multiple and regioselective alkylation on the exo nitrogen of pyridinium N-(heteroaryl)aminides with several polybromo compounds, followed by a clean N-N bond reduction of the corresponding pyridinium salts, provides an easy and general method to obtain the title compounds.
