An efficient way to prepare functionalized 8-iodo-2-trifluoromethanesulfonyloxyquinolines
is presented. The iodo functionality could be selectively converted
into other residues via an iodine-magnesium exchange reaction.
In addition, the trifluoromethanesulfonate functionality was used
as a leaving group in Negishi cross-coupling reactions.
