| | (S)-(+)-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 | white to light yellow crystal powde | | Uses | The S enantiomer of binaphthol derivative as chiral quenching agent. | | Uses | Used as a chiral Bronsted acid catalyst in the enantoselective Mannich reaction. | | 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.] |
