## 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
