Application

(S)-(+)-Hajos-Parrish diketone can be used as a reactant in:
  • The total synthesis of steroidal alkaloids cortistatins.
  • The stereoselective preparation of hydroanthracenol and related polycyclic compounds via Ti(Oi-Pr)4-promoted photoenolization Diels-Alder reaction.
  • The synthesis of γ,γ-disubstituted allyldiboron compounds by reacting with allylic 1,1-diboronate reagents via Cu-catalyzed borylation and 1,2-addition reaction.
