Application

trans-4-(tert-Butyldimethylsiloxy)-1-buten-1-ylboronic acid pinacol ester can be used as a substrate:
  • In the catalyst-free Zweifel olefination of alkenyl boronic esters using triorganocerium reagents.
  • In the study of carbosulfenylation reactions of alkenylboronates.
  • To prepare chiral tris(boronates), which are important building blocks for preparing synthetically challenging compounds.
