The trimethylsilyl trifluoromethanesulfonate accelerated Diels-Alder reaction between 1,3-dimethyl-4-(phenylsulfonyl)-4H-furoindole (3) and 5,6-dihydropyridones (10) shows high regioselectivity, yielding carbazole 11 upon hydrolytic workup.Carbazole 11b has been successfully converted to the pyridocarbazole alkaloid ellipticine (1).
