    • 2 was added into the mixture. Finally, trans-isoeugenol (or trans-anethole) was added dropwise to the reaction mixture. The temperature was kept to 70 °C under inert atmosphere (nitrogen) for 10 h. After complete conversion, as indicated by TLC, the crude product was purified by column chromatography without previous extraction to obtain tetrahydroquinolines 9a-f.
