Abstract:An imidazolidin-2-one chiral auxiliary mediated acetate aldol reaction was explored in the enantioselective synthesis of (S)-dapoxetine (SSRI). The diastereoselective aldol adduct was transformed to highly enantiopure (S)-dapoxetine with overall good yield.
Keywords:Asymmetric reaction  Acetate aldol  Dapoxetine  Chiral auxiliary
