| | (R)-(-)-1,1'-Binaphthyl-2,2'-diyl hydrogenphosphate Usage And Synthesis |
| Reaction |
- Asymmetric hetero Diels-Alder reaction catalyzed by chiral lanthanide(III) complex.
- Highly efficient Mannich reaction.
- Acidic Resolving agent for certain amine/racemic mixtures.
| | Chemical Properties | off-white powder | | Uses | The R enantiomer of binaphthol derivative as chiral quenching agent. | | Uses | A chiral ligand used in hydrocarboxylation reactions. Complexes with rhodium and mediates the asymmetric dipolar cycloaddition of diazo compounds. A number of racemic amines which have proven difficult to separate have been resolved with this chiral acid. Palladium derivatives have been used in asymmetric hydrocarboxylations, and rhodium derivatives have been used in dipolar cycloadditions. | | Uses | chiral ligand for hydroxycarboxylations, complexes rhodium | | Purification Methods | Recrystallise it from EtOH. Reflux for 3hours in N NaOH is required to hydrolyse the cyclic phosphate. [Jacques et al. Tetrahedron Lett 4617 1971, Arnold et al. Tetrahedron 24, 343 1983.] |
