合成路线1
该中间体在本合成路线中的序号:(IV)The condensation of trifluoroacetoacetic acid ethyl ester (I) with cyclohexane-1,3-dione (II) and 3-cyanobenzaldehyde (III) by means of ammonium acetate in refluxing ethanol gives the octahydroquinolone (IV), which is hydrolyzed at its ester group by means of LiOH in hot ethanol/water to yield the corresponding carboxylic acid (V). Finally, this compound is dehydrated by means of TsOH in refluxing toluene to afford the target intermediate (rac)-4-(3-cyanophenyl)-5-oxo-2-(trifluoromethyl)-1,4,5,6,7,8-hexahydroquinoline-3-carboxylic acid (VI).
