An improved procedure for the preparation of aromatic heterocyclic N-oxides was written by Rhie, Soo Young; Ryu, Eung K.. And the article was included in Heterocycles on February 1,1995.Reference of 35139-67-4 The following contents are mentioned in the article:
Nitrogen-containing heterocyclic compounds gave their N-oxides in excellent yields by reaction with m-chloroperbenzoic acid in DMF/MeOH in the presence of HF. The presence of HF and MeOH is crucial for the reaction. This study involved multiple reactions and reactants, such as 2,6-Diamino-4-chloropyrimidine-1-oxide (cas: 35139-67-4Reference of 35139-67-4).
2,6-Diamino-4-chloropyrimidine-1-oxide (cas: 35139-67-4) belongs to pyrimidine derivatives. Heterocyclic compounds bearing the pyrimidine core are of tremendous interest as they constitute an important class of natural and synthetic compounds exhibiting diverse useful biological activities that hold attractive potential for clinical translation as therapeutic agents in alleviation of a myriad of diseases. A Cu-catalyzed and 4-HO-TEMPO-mediated [3 + 3] annulation of commercially available amidines with saturated ketones enables an efficient and facile synthesis of structurally important pyrimidines via a cascade reaction of oxidative dehydrogenation/annulation/oxidative aromatization.Reference of 35139-67-4
