(R)-(-)-1,1'-Binaphthyl-2,2'-diyl hydrogenphosphate Chemical Properties,Uses,Production

Reaction

  1. Asymmetric hetero Diels-Alder reaction catalyzed by chiral lanthanide(III) complex.
  2. Highly efficient Mannich reaction.
  3. Acidic Resolving agent for certain amine/racemic mixtures.

Chemical Properties

off-white powder

Uses

chiral ligand for hydroxycarboxylations, complexes rhodium

Uses

The R enantiomer of binaphthol derivative as chiral quenching agent.

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.]
