Irradiation (u>345 nm) of catalytic amounts of 2,4,6-triphenylpyrylium tetrafluoroborate (TPT) in a CH 2 Cl 2 solution of N-aryl imines and a-methylstyrene or styrene produced the corresponding [4+2] cycloaddition products, tetrahydroquinoline derivatives, in good yield. The reaction was controlled

Hexafluoroisopropanol and trifluoroethanol are found to promote imino-Diels-Alder reactions of the N-aryl aldimine 1 with alkyl vinyl ethers to afford the corresponding tetrahydroquinolines in good yields without Lewis acid under mild and neutral conditions. The reaction is also efficient in a three
