Descripción

Application

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

Both (+)- and (-)-forms are precursors to B-allyldiisopinocampheylborane derivatives, which are subsequently reacted with aldehydes to give homoallylic alcohols and β-amino alcohols of high enantiomeric excess.
