Application

(S)-2-(Methoxydiphenylmethyl)pyrrolidine is a diphenylprolinol methyl ether, which can be used as a catalyst to synthesize:
  • Enantioselective ketones via intermolecular asymmetric Michael addition of aldehydes to nonactivated enones.
  • Stereoselective chiral bipyrazolidin-3-one derivatives by dipolar cycloaddition reaction of azomethine imines with α, β-unsaturated aldehydes.
  • Enantioenriched spiro nitrogen heterocycles via asymmetric nucleophilic epoxidation of α-ylideneoxindole esters.
  • Optically active secondary alcohols by asymmetric addition of Et2Zn to various aldehydes.
