tert-Butyldimethylsilyl trifluoromethanesulfonate is a nucleophilic reagent that forms an addition product with metal carbonyls. It can be used for the synthesis of indacaterol maleate, which is a phosphite prodrug for the treatment of asthma and chronic obstructive pulmonary disease. Tert-butyldimethylsilyl trifluoromethanesulfonate has been shown to catalyze asymmetric hydrogenation reactions in the presence of ammonia as a chiral auxiliary. This reagent has also been shown to inhibit the growth of bacteria and fungi through its ability to inhibit protein synthesis.

Trialkylsilyl Blocking Agent
Used as a protecting group for reactive hydrogens in alcohols, amines, thiols, and carboxylic acids. Organosilanes are hydrogen-like, can be introduced in high yield, and can be removed under selective conditions. They are stable over a wide range of reaction conditions and can be removed in the presence of other functional groups, including other protecting groups. The tolerance of silylated alcohols to chemical transformations summary is presented in Table 1 of the Silicon-Based Blocking Agents brochure.
