Pyridines and 5H-Benzopyranopyridines Derived from Halochalcones
Latif, N.,Mishriky, N.,Haggag, B.,Basyouni, W.
, p. 1230 - 1234 (2007/10/02)
The halochalcones (1a-c) react with malononitrile in the presence of ammonium acetate to give the corresponding 2-amino-4,6-diaryl-3-cyano-pyridines (2a-c), whereas with ethyl cyanoacetate the 4,6-diaryl-3-cyano-2-pyridones (3a-c) are obtained.On the cont
