合成路线1
该中间体在本合成路线中的序号：(VII)The cyclization of 2-methylphenyl isothiocyanate (I) with 2-aminoacetaldehyde dimethylacetal (II) in methanol gives the 1-(2-methylphenyl)imidazole-2-thiol (III), which is condensed with 3-bromopropanol (IV) by means of NaOH in refluxing water to yield the sulfide (V). The asymmetric oxidation of sulfide (V) with Ti(O-iPr)4, cumene hydroperoxide (CHP) and (R)-(-)-mandelic acid as chiral catalyst in dichloromethane affords the (S)-sulfinyl derivative (VI), which is treated with Ms-Cl to provide the expected mesylate (VII). Finally, this compound is condensed with the sodium salt of 6-hydroxy-1,2,3,4-tetrahydroquinolin-2one (VIII) to give the target compound.
