(A) Transferring group scope. (B) Synthesis of alkyne-labeled 2 via derivatizable pyridinium salt 1c. (C) LC/MS TIC traces of crude reaction mixtures. a 120 min reaction time. [GSH] = 5 mM, [1a] = 20 mM. b % conversion estimated by TIC, average of 2–3 experiments. Ratio of mono/di label >20:1 unless stated otherwise. c Isolated after HPLC purification, average of three experiments.
