- An alternate route to 2-amino-3-nitro-5-bromo-4-picoline: Regioselective pyridine synthesis via 2-nitramino-picoline intermediate
-
The 2-nitramino functionality in 2-nitramino-4-picoline was successfully exploited not only as a protecting group but also as a directional handle to afford an efficient, atom-economic, and regioselective synthesis of 2-amino-5-bromo-3-nitro-4-picoline (4), a precursor for a drug candidate in development.

- Substituent Effects on the Isomer Ratios in the Rearrangement of Some 2- and 4-Nitraminopyridines
-
The preparation, and rearrangement in 92percent sulfuric acid, of 4-X-2-nitramino- (1), 2-X-4-nitramino- (2), and 6-X-2-nitramino-pyridines (3) is reported (X=H,Me,MeO,Br,Cl,CO2H).The product isomer ratios can be explained by differential electronic stabilization of the appropriate ? complexes for aromatic nitration and steric effects seem relatively unimportant.Deuteration had no effect on the product distribution
