Application
Methylboronic acid can be used as a reagent:
- In the palladium-catalyzed Stille and Suzuki-Miyaura cross-couplings.
- In the microwave-heated heterogeneous palladium (Pd)-catalytized reactions.
- In ruthenium (Ru)-catalyzed silylation reactions
- To prepare bis(aminotropone) titanium (Ti) catalysts for ethylene polymerizations.
- In the enantioselective asymmetric bromoaminocyclization and bromoaminocyclization using amino-thiocarbamate catalysts.
- To prepare common building blocks for pharmaceuticals and agrochemicals.
- To prepare chrysin analogs by Suzuki-Miyaura coupling reactions.
- To prepare casein kinase I inhibitors.
- In the divergent C-H functionalizations directed by sulfonamide pharmacophores in drug discovery.
- In the synthesis of unsymmetrical monosulfides from disulfides via copper-catalyzed coupling with boronic acids.
- In a palladium-catalyzed coupling with enol tosylates.
- For derivatizing many carbohydrates and biologically active compounds for GLC analysis.

A facile and efficient enantioselective bromoaminocyclization of unsaturated sulfonamides has been developed using an amino-thiocarbamate catalyst. A range of enantioenriched pyrrolidines were prepared with up to 99% yield and 99% ee. The corresponding lactams could be obtained through oxidation of
