An efficient improve for the Krohnke reaction: One-pot synthesis of 2,4,6-triarylpyridines using raw materials under microwave irradiation
A series of 2,4,6-triarylpyridines have been prepared by the one-pot reaction of aldehydes with aromatic ketones in the presence of ammonium acetate under microwave irradiation without catalyst. This method has the advantage of easier workup, shorter reaction time, higher yield, and environment-friendly.
