An improved procedure for the preparation of aromatic heterocyclic N-oxide is described.Nitrogen containing heterocyclic compounds gave their N-oxides in excellent yields by the reaction of m-CPBA in DMF/MeOH in the presence of HF in a short time under mild reaction conditions.The presence of HF and MeOH is crucial for the reaction.
Synthesis and antifungal activity evaluation of 3-hydroxyimidazo[1,2-a]pyridine and 3-hydroxyimidazo[1,2-a]pyrimidine derivatives

A series of 16 imidazo[1,2-a]pyridine and imidazo[1,2-a]pyrimidine derivatives was synthesized and tested on several species for 'in vitro' fungicide activity.
Synthesis of some pyrimidine N-oxides

Various monosubstitudes pyrimidines and methylpyrimidines were N-oxidized with a number of different peracids.In general, they are more susceptible to side reactions accompanying N-oxidation (i.e., decomposition, annular carbon oxidation, ring opening) than other ?-deficient diazine and triazine analogs.Unsymmetrical pyrimidines, which can potentially yield two isomeric products, were N-oxidized preferentially at the site para to strong electron-donating substituents.Weaker ringactivating groups, such as methyl, are mainly ortho directing and only aid in the N-oxidation of pyrimidine nuclei having ortho/para-directing substituents.
SYNTHESES AND TRANSFORMATIONS OF SOME HETEROCYCLIC HYDROXYLAMINES
Tomazic, Alenka,Tisler, Miha,Stanovnik, Branko
, p. 1787 - 1794 (2007/10/02)
Syntheses of some hydroxylaminoazines, their quaternized derivatives or N-oxides and N-amino compounds are described.Several transformations of these compounds and cyclization reactions are presented.
