(Trifluoromethyl)thiolation of 2-alkynylbenzoates: An efficient route to 4-[(trifluoromethyl)thio]-1H-isochromen-1-ones
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
