Magnesium Methoxide-Assisted Synthesis of 2,4,6-Triaryl Pyridines
摘要:
A new three-component reaction of chalcones, ketones, and ammonia assisted by magnesium methoxide is described. The corresponding 2,4,6-triaryl pyridines (Krohnke pyridines) are formed in fair to good yields (34-76%) within 3h. The method also provides a facile way to synthesize 2(6)-difluoromethyl pyridines via an interesting mechanism.
