An efficient synthesis of 2,4,6-triarylpyridines is described. Heating a mixture of an acetophenoneoxime and an aldehyde under solvent-free conditions afforded Krohnke pyridines in excellent yields. In this method acetophenoneoximes are directly used for the preparation of Krohnke pyridines under metal-free conditions.
An efficient synthesis of 2,4,6-triarylpyridines is described which involves heating a mixture of an acetophenone oxime and an epoxy styrene under neutral, solvent-free conditions. Krohnke pyridine products are obtained in excellent yields. (C) 2014 Published by Elsevier Ltd.

An efficient and green synthesis of 2,4,6‐triarylpyridines by a one‐pot three‐component condensation of aromatic aldehydes, substituted acetophenones, and ammonium acetate without catalyst at 130°C under solvent‐free conditions is described. This method offers several advantages such as simple procedure, easy work‐up, short reaction time, low cost, environmentally friendly conditions, and moderate to high yields.
