Application

Benzo[b]thien-3-ylboronic acid can be used:
  • To prepare thienyl substituted pyrimidine derivatives as potent antimycobacterial compounds.
  • To prepare 3-O-protected 17-heteroaryl-3-hydroxyestra-1,3,5,16-tetraene-16-carbaldehyde, which in turn is used for the synthesis of heteroarenes-annelated estranes.
  • As a substrate in the study of metal-free coupling reactions of allylic alcohols with heteroaryl boronic acids.
  • As a starting material for the preparation of thienyl based quinoline and pyridine ligands, which are further used to synthesize platinum complexes.
