该中间体在本合成路线中的序号：(II)Alkylation of 2-mercapto-1-o-tolylimidazole (I) with the bromopropoxy tetrahydroquinolinone (II) in the presence of DBU gave sulfide (III). Then, asymmetric oxidation of (III) with cumene hydroperoxide and titanium tetraisopropoxide, using D-diethyl tartrate as the chiral auxiliary produced the target (S)-sulfoxide with low enantiomeric excess. Several recrystallizations from EtOH-EtOAc yielded the enantiomerically rich compound.
