AbstractA simple, efficient, and green method of preparation for the synthesis of highly substitutedpyridines by multicomponent reaction of acetophenones, aldehydes, and ammonium acetate using activated Fuller’s earth as an effective and reusable heterogeneous catalyst is described. The advantages of the present protocol include simple procedure with an easy workup procedure, mild reaction conditions
