Application

Both (+)- and (-)-forms are precursors to B-allyldiisopinocampheylborane derivatives, which are subsequently reacted with aldehydes to give homoallylic alcohols[1] and β-amino alcohols[2] of high enantiomeric excess.[3]
Reactant involved in:
  • Oxidative cyclization and alkylation for synthesis of ionomycin
  • Intramolecular conjugate addition for tetrahydropyran synthesis
  • Aldol addition and Suzuki coupling reactions
  • Allylation
  • Synthesis of alkanols
