合成路线1
该中间体在本合成路线中的序号:(I)The reaction of 1-indanone (I) with sodium azide in acetic acid/sulfuric acid gives the tetrahydroquinolone (II), which is reduced with LiAlH4 in THF, yielding the tetrahydroquinoline (III). The reaction of (III) with NaNO2 and sulfuric acid afords the N-nitroso derivative (IV), which is reduced wiith LiAlH4 in THF to the N-amino compound (V). The reaction of (V) with cyclohexane-1,3-dione (VI) gives the monohydrazone (VII), which is cyclized by means of HCl in refluxing acetic acid, yielding the tetracyclic compound (VIII). The reaction of (VIII) with dimethylamine and paraformaldehyde in hot acetic acid provides compound (IX), which is treated with 2-methylimidazole (X) in refluxing water to afford racemic cilansetron (XI). Finally, this racemate is submitted to optical resolution with di-p-toluyl-D-tartaric acid or D-pyroglutamic acid.

合成路线3
该中间体在本合成路线中的序号:(I)The reduction of 1-indanone (I) with NaBH4 in methanol gives 1-indanol (II), which is brominated with Tms-Br in chloroform to yield 1-bromoindane (III) (1). The condensation of (III) with triethyl phosphonoacetate (IV) and NaH in DMF affords 2-(diethoxyphosphoryl)-2-(1-indanyl)acetic acid ethyl ester (V), which is treated with paraformaldehyde and K2CO3 in refluxing THF to provide 2-(1-indanyl)acrylic acid ethyl ester (VI). The hydrolysis of (VI) with NaOH in acetone/water gives the corresponding acrylic acid (VII), which is condensed with thioacetic acid (VIII) in refluxing chloroform to yield 3-(acetylsulfanyl)-2-(1-indanyl)propionic acid ethyl ester (IX) as a mixture of the two (R,R)+(S,S) and (R,S)+(S,R) racemates. These two racemates are easily separated by HPLC affording the desired (R,R)+(S,S)-(X) racemate. The condensation of (X) with L-tryptophan methyl ester (XI) by means of EDC and HOBT in THF/chloroform to provide a diastereomeric mixture (R,R,S)+(S,S,S) of compounds that is separated by HPLC to provide the desired (R,R,S) diastereomer (XII). Finally, this compound is hydrolyzed with NaOH in methanol/water to furnish the target tryptophan derivative.
