该中间体在本合成路线中的序号：(X)

The Friedel-Kraft's reaction of benzene (I) and 3,4-dichlorobenzoyl chloride (II) by means of AlCl3 in dichloromethane gives 3,4-dichlorobenzophenone (III), which is condensed with diethyl succinate (IV) by means of potassium tert-butoxide in tert-butyl alcohol yielding ethyl 3-ethoxycarbonyl-4-(3,4-dichlorophenyl)-4-phenylbut-3-enoate (V). Hydrolysis of (V) with HBr in refluxing acetic acid affords 4-(3,4-dichlorophenyl)-4-phenylbut-3-enoic acid (VI), which is hydrogenated with H2 over Pd/C in ethyl acetate giving 4-(3,4-dichlorophenyl)-4-phenylbutanoic acid (VII), which is converted into the corresponding acyl chloride (VIII) with refluxing SOCl2. Cyclization of (VIII) with AlCl3 in CS2 yields 4-(3,4-dichlorophenyl)-3,4-dihydro-1-(2H)-naphthalenone (IX), which is treated with methylamine and TiCl4 in THF affording the corresponding Schiff base (X). Finally, this compound is reduced with H2 over Pd/C in THF.

该中间体在本合成路线中的序号：(II)

The reaction of 4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydronaphthalen-1-one (I) with methylamine by means of TiCl4 in toluene gives the corresponding imine (II), which is reduced with H2 over 5% Pd/graphite, yielding a 12:1 mixture of (??(cis)(III) and (?)(trans)(III). This mixture was resolved by a treatment with (D)-mandelic acid, crystallization of the resulting salt, and treatment with NaOH in toluene/water to afford the target (+)(S,S)(cis)-sertraline.
