The trimethylsilyl trifluommethanesulfonate accelerated Diels-Alder reaction between 1,3-dimethyl-4-(phenylsulfonyl)-4H-foro[3,4-b]indole (3) and 5,6-dihydropyridones (10) shows high regioselectivity, yielding carbazole 17 upon hydrolytic workup. Carbazole 77b has been successfully converted to the
