## Abstract An efficient synthesis of enaminones **1a‐c** is reported. Compounds **1a‐c** reacted with diefhyl‐3‐amino‐2‐cyanopenten‐1,5‐dicarboxylate (**3**) to yield the benzonitriles **6**. On the other hand, the reaction of **la‐c** with 3‐amino‐2‐cyano‐2‐pentene dinitrile (**7**) afforded a mi
## Abstract 1‐Substituted‐3‐dimethylaminopropenones **1a‐d** reacted with acetylacetone and with ethyl acetoacetate to yield regioselectively 2,3,6‐trisubstituted pyridines. Refluxing **1a‐d** in acetic acid/ammonium acetate resulted in the formation of 6‐substituted‐3‐aroylpyridines, whereas reflu
