Nitropyridines: VI. Synthesis of 2-aryl(hetaryl)- and 2,3-polymethylene-5-nitropyridines
摘要:
Previously unknown 2-aryl-, 2-hetaryl-, and 2-cyclopropyl-5-nitropyridines and 2,3-polymethylene-5-nitropyridines were synthesized by reactions of 1-methyl-3,5-dinitropyridin-2(1H)-one with various cyclic and acyclic ketones in the presence of ammonia.
