Questions And AnswerBack Directory
[Reaction]

  1. Phosphine-catalyzed intra-and intermolecular gamma-addition of nitrogen nucleophiles to allenoates and alkynoates.
  2. Catalytic asymmetric construction of the tryptanthrin skeleton via enantioselective decarboxylative [4+2] cyclization.
  3. Catalytic, enantioselective carbon-oxygen bond formation – phosphine-catalyzed synthesis of benzylic esters via oxidation of benzylic C-H bonds.
  4. Use of a new spirophosphine to achieve catalytic, enantioselective [4+1] annulations of amines with allenes to generate dihydropyrroles.
