• 용도

  (S)-3,3′-Bis(triphenylsilyl)-1,1′-binaphthyl-2,2′-diyl hydrogenphosphate can be used as a catalyst:
  
  • In the synthesis of 1,3-dioxolochroman skeletons by reacting 3-methyl-2-vinylindoles with ortho-quinone methides.
  • In the exo-selective cyclization of mupirocin methyl ester.
  • In the kinetic resolution of cyclic aliphatic syn-1,3-diols, which are used as valuable building blocks.
  
  

• 화학 반응

  1. Chiral phosphoric acid catalyst used for the highly enantioselective Friedel-Crafts reaction of indoles with imines.
  2. Chiral phosphoric acid catalyst used for the highly enantioselective Friedel-Crafts reaction of pyrrole derivatives with N-acyl imines.
  3. Chiral phosphoric acid catalyst used for the enantioselective transfer hydrogenation of hydroxylactams providing enantioenriched tetrahydro-β-carbolines (in dioxane) at room temperature (up to 94% yield, 90% ee).
  4. [Rh2(OAc)4]/chiral phosphoric acid catalyst used for the enantioselective symmetric, three-component reaction of diazo compounds with imines and water yielding β-amino-α-hydroxy acid derivatives.
  5. Enantioselective desymmetrization of prochiral allenic diols via cooperative catalysis of Pd(OAc)2 and a chiral phosphoric acid.
