It is applied as a reagent for synthesis of medium-ring amines via N-alkylation, e.g. with ω-bromo alkanols under Mitsunobu conditions (DEAD/PPh3), and cyclization of the resulting ω-bromo alkylsulfonamides (Cs2CO3/Bu4NI). It is a carbonic anhydrase inhibitor. It is employed as a reactant involved in synthesis of cyclic nitrogen compounds via intramolecular hydroamination, pentacyclic lycopodium alkaloid huperzine-Q2, pyrrolidines, intermolecular C-H insertion reactions and reactant involved in intermolecular amination of allyl alcohols.
