(R)-(-)-3,3'-BIS(TRIPHENYLSILYL)-1,1'-BINAPHTHYL-2,2'-DIYL HYDROGENPHOSPHATE, 95% Usage And Synthesis
  • Reaction
    1. A chiral phosphoric acid catalyst providing a convenient strategy for the enantioselective construction of protected primary amines and a highly stereoselective method for the reductive amination of heterocyclic amines.
    2. Chiral phosphoric acid used for the enantioselective Biginelli and Biginelli-like reactions.
    3. Chiral phosphoric acid organocatalyst used in the asymmetric, three-component Povarov reaction involving 2-hydroxystyrenes. An efficient method to access structurally diverse cis-disubstituted tetrahydroquinolines in high stereoselectivities of up to >99:1 dr and 97% ee.
    4. A gold/chiral phosphoric acid catalyst used for the highly stereoselective, three-component reaction of salicylaldehydes, anilines, and alkynols to give aromatic spiroacetals in high yields and stereoselectivities.
    5. The first highly enantioselective catalytic protocol for the reductive coupling of ketones and hydrozones.
    6. Reagent-controlled regioselectivity enabled by dual activation.
