triflates using a newly discovered reagent in presence of a fluoride source. The reactions are generally complete within a few minutes at room temperature. The mild conditions allow the late-stage O-triflation of complex peptides bearing challenging side chains like arginine and histidine. We show that aryl triflates can be an interesting moiety for medicinal chemistry.
