合成路线1
该中间体在本合成路线中的序号:(XXXVIII)The secondary alcohol (XXXII) is treated with phenyllithium in THF (to open the cyclic carbonate and form the benzoyloxy group) and oxidized with tetrapropylammonium perruthenate (TPAP) to give the benzoyloxyketone (XXXIII). Enolization of ketone (XXXIII) with potassium tert-butoxide affords the potassium enolate (XXXIV), which is oxidized with phenylseleninic anhydride and acetylated with acetic anhydride in DMAP to give the alpha-acetoxyketone (XXXV). Further desilylation of (XXXV) with tris(diethylamino)sulfoxonium difluorotrimethylsiliconate (TASF) in THF yields the secondary alcohol (XXXVI), which is condensed with Ojima's beta-lactam (XXXVII) by means of lithium hexamethyldisilazane (LHMDS) in THF to afford protected paclitaxel (XXXVIII). Finally, this compound is deprotected first with HF in pyridine to eliminate the triethylsilyl (TES) group and then hydrogenated with H2 over Pd/C in ethanol to eliminate the BOM group.

合成路线2
该中间体在本合成路线中的序号:(XVII)A new synthesis of [14C]-labeled paclitaxel has been published: The protection of L-threonine methyl ester (I) with tert-butoxydiphenylchlorosilane (BPS-Cl) gives the compound (II), which is condensed with [14C]-labeled benzaldehyde (III), yielding the imine (IV). The cyclization of (IV) with acetoxyacetyl chloride (V) by means of triethylamine affords the azetidinone (VI), which is deprotected with tetrabutylammonium fluoride to the hydroxy ester (VII). The dehydration of (VII) with p-toluenesulfonyl chloride and triethylamine affords the unsaturated ester (VIII), which by ozonolysis is converted to the oxalimide (IX). Elimination of the oxalyl group with hydrazine gives the labeled azetidinone (X), which is deacetylated to the hydroxyazetidinone (XI) and protected with triethylchlorosilane (TES-Cl) to (XII). The benzoylation of (XII) with benzoyl chloride (XIII) and dimethylaminopyridine (DMAP) yields the corresponding benzoylated compound (XIV), which is then condensed with triethylsilyl-baccatin III (XV) by means of butyllithium to afford silylated labeled paclitaxel (XVI). Finally, this compound is deprotected with HCl. The intermediate silylated baccatin III (XV) is obtained from paclitaxel (XVII) by hydrogenolysis with NaBH4 to baccatin III (XVIII) and silylation with triethylsilyl chloride to (XV).

该中间体在本合成路线中的序号:(Ia)Several partial syntheses of docetaxel have been described: The selective hydrolysis of Taxol A (I, R = Ph), Taxol B (I, R = C(Me)=CHMe) or Taxol C (I, R = C5H11) with NaHCO3 in THF/water gives the corresponding 10-deacetyl derivatives (II), which by selective silylation with triethylsilyl chloride in pyridine are converted into the 10-deacetyl-2',7-bis(triethylsilyl) compounds (III). The reaction of compounds (III) with zirconocene chloride hydride [bis(cyclopentadienyl)zirconium chloride hydride] in THF afford the corresponding imino derivatives (IV), which, without isolation are hydrolyzed and desilylated by a treatment with concentrated aqueous HCl in ethanol giving 10-deacetyltaxolamine (V). Finally, this compound is acylated at the amino group by a treatment by di-tert-butyl dicarbonate and NaHCO3 in ethyl acetate/water.
