Application

trans-2-Chloromethylvinylboronic acid pinacol ester is a common reactant of Suzuki coupling reaction. It can be used to prepare:
  • Readout reagent that helps in providing qualitative and quantitative readouts in enzyme biomarker detection assays.
  • Boronated enynes, which on Au(I) catalyzed cycloisomerization yield various dienyl boronates.
  • α-Methyl-substituted boronates for the allylation of ketones to yield homoallylic tertiary alcohols.
