Description and Uses

The product may be used as a ligand in:

• Iridium-catalyzed allylic etherification of acyclic, achiral allylic carbonates with potassium silanolates to form chiral allylic alcohols.
• Palladium-catalyzed asymmetric allylic cyclisation of N-tosyl and N-benzyl carbonates to form the corresponding pyrrolidine and piperidine derivatives, respectively.
• Intramolecular iridium-catalyzed allylic cyclizationof (E)-allylic methyl carbonates to form 2,5-trans/cis pyrrolidine derivatives.
