Abstract
The incorporation of the (trifluoromethyl)thio group into the isocoumarin scaffold through a Lewis-acid-mediated electrophilic cyclization reaction of 2-(2-alkynyl)benzoates with trifluoromethanesulfanylamide is reported. The transformation proceeds well in the presence of BiCl3 and BF3·Et2O under mild conditions to give 4-[(trifluoromethyl)thio]-1H-isochromen-1-ones regioselectively and in good yields.
