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.

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).

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.

The reaction of taxol (I) with benzyloxycarbonyl chloride and DIEA in dichloromethane gives the protected compound (II), which is treated with DAST in the same solvent to yield the cyclopropa taxol (III). The hydrogenolysis of (III) with H2 over Pd/C affords compound (IV), which is deacylated with tetrabutylammonium borohydride in dichloromethane to provide the cyclopropa baccatin (V). The acylation of (V) with azetidinone (VI) by means of BuLi in THF gives the silylated taxoid (VII), which is finally desilylated with HCl in acetonitrile to afford the target compound.

Acylation of paclitaxel (I) with 2,3-O-isopropylideneglyceryl chloroformate (II) produced the 2',7-bis-carbonate (III). Subsequent acid hydrolysis of the acetonide groups of (III) furnished the corresponding bis-(dihydroxypropyl)carbonate (IV).

In an alternative method, paclitaxel (I) was acylated with allyl chloroformate (V) to afford the bis-carbonate (VI). Dihydroxylation of both allyl groups of (VI) was accomplished by treatment with tert-butyl hydroperoxide producing (IV). The 2'-ester of (IV) was finally removed upon stirring in a NaHCO3-neutralized solution at room temperature.

Paclitaxel (I) was protected as the 2'-(triethylsilyl) derivative (II) and then converted to the 7-methylsulfanylmethyl ether (III) by treatment with dimethyl sulfide and benzoyl peroxide. Subsequent desilylation of (III) using aqueous acetic acid or HCl in H2O/CH3CN furnished the desired 7-O-methylsulfanylmethyl paclitaxel. Alternatively, the title compound was also obtained by direct methylsulfanylmethylation of paclitaxel.

Malic acid (I) was protected as the 1,2-O-isopropylidene derivative (II) upon treatment with acetone in the presence of acid catalyst. Condensation of (II) with paclitaxel (III) using diisopropylcarbodiimide and DMAP produced the 2'-ester (IV). After hydrolytic cleavage of the isopropylidene protecting group of (IV), conversion to the corresponding sodium carboxylate salt furnished the title compound.
