TBSAB was used for the sulfation and sulfamation of a wide range of benzyl alcohols, benzylamines, amino acids, and carbohydrates. [44] TBSAB has also been used for the chemoselective sulfation of steroids affording the corresponding sulfated steroid molecules such as, estrone sulfate, pregnenolone sulfate, and pregnanediol sulfate. TBSAB has also found use as a reagent to install aniline N-sulfamates prior to their intermolecular rearrangement. A summary of the scope and range of sulfated molecules achievable with Bu3NSO3 complex are listed in Table .
