Electrophilic Fluorination of a Highly Functionalized Pyrrole

Keith Douglas Barnes; Yulin Hu; David Allen Hunt

Abstract Bromine-lithium exchange of 3-bromo-1 -(trilsopropylsilyl) pyrrole 6 followed by treatment with N-fluorobenzenesulfonimide gave the fluoropyrrole 8. Application of this methodology to the highly functionalized pyrrole 1 afforded the fluoropyrrole 4, which was found to be inaccessible by other approaches.
