• Reaction

  1. Biaryl bisphosphine ligand. The H8-BINAP ligand, as the ruthenium complex, catalyzes hydrogenation of unsaturated carboxylic acids to a higher ee than does BINAP.
  2. The ruthenium catalyzed hydrogenation of aryl propenoic acid to produce the drug Ibuprofen.
  3. Rhodium catalyzed asymmetric regioselective 1,4-addition of arylboronic acids to 3-substituted maleimides.
  4. Ligand for palladium-catalyzed enantioselective hydrogenation of substituted indoles.
  5. Rhodium-catalyzed enantioselective cyclization of γ-alkynylaldehydes with acyl phosphonates.
  6. Enantioselective synthesis of axially chiral 1-arylisoquinolines by Rh-catalyzed [2+2+2] cycloaddition.
  7. Enantioselective synthesis of 2,3-disubstituted indolines through Bronsted acid/Pd-complex-promoted tandem reactions.
  8. Dehydration triggered asymmetric hydrogenation of 3-(α-hydroxyalkyl)indoles
  9. Iridium-catalyzed [2+2+2] cycloaddition of α,ω-diynes with arylisocyanates
  10. Asymmetric hydrogenation of 3-(toluenesulfonamidoalkyl)-indoles
  11. Asymmetric Rh(I)-catalyzed intramolecular [3+2] cycloaddition of 1-yne-vinylcyclopropanes for bicyclo[3.3.0] compounds with a chiral quaternary carbon stereocenter.
  12. Enantioselective intermolecular [2+2+2] cycloadditions of ene-allenes with allenoates.
  13. Rh-catalyzed one-pot intermolecular [2+2+2] trimerization/asymmetric intramolecular [4+2] cycloaddition of two aryl ethynyl ethers and 5-alkynals.
  14. Rh-catalyzed regio-, diastereo-, and enantioselective [2+2+2] cycloaddition of 1,6-enynes with acrylamides.
