An Efficient and Short Synthesis of 4-Aryl-3-methyltetrahydroquinolines from N-Benzylanilines and Propenylbenzenes through Cationic Imino Diels-Alder Reactions

[摘要]：A new, simple protocol for the BF3 center dot OEt2-catalyzed synthesis of diverse 3-methyl-4-aryl-1,2,3,4-tetrahydroquinolines using easily available starting materials and renewable phenylpropenoid reagents is described. These compounds could serve as interesting models in pharmacological studies.
