A simple and efficient method for the synthesis of derivatives of cyclopent-2-en-1-one is presented. Aromatic aldehydes reacted with aliphatic ketones in the presence of thionyl chloride in anhydrous ethanol to give seven derivatives of 2-cyclopenten-1-one in one step with reasonable yields. The structures of the products were established.
