An Alternative Synthetic Approach to 3-Alkylated/Arylated 5-Nitropyridines
An alternative method for the synthesis of 3-alkylated/arylated 5-nitropyridines was developed involving a three-component ring transformation of 3,5-dinitro-2-pyridone on treatment with aldehyde in the presence of ammonium acetate. This method facilitate

C-H arylation of pyridines: High regioselectivity as a consequence of the electronic character of C-H bonds and heteroarene ring
We report a new catalytic protocol for highly selective C-H arylation of pyridines containing common and synthetically versatile electron-withdrawing substituents (NO2, CN, F and Cl). The new protocol expands the scope of catalytic azine functi
INVERSE ELECTRON DEMAND DIELS-ALDER REACTIONS OF 5-NITROPYRIMIDINE WITH ENAMINES. SYNTHESIS OF 3-NITROPYRIDINE DERIVATIVES
The reaction of cyclic and non-cyclic enamines with 5-nitropyrimidine has been studied.Many enamines react in an inverse electron-demand Diels-Alder reaction, leading to the formation of 3-nitropyridines.N,S-ketene acetals were also found to react with 5-nitropyrimidines.The mechanism of the reaction will be discussed.
