合成路线1
该中间体在本合成路线中的序号:(IV)Palladium-catalyzed coupling of 4-bromobenzophenone (I) with methyl acrylate (II) afforded 4-benzoylcinnamic ester (III), which was hydrolyzed to acid (IV) with NaOH. Condensation with taxane derivative (V) in the presence of DCC and DMAP then provided the target ester.

合成路线2
该中间体在本合成路线中的序号:(XI)Heck coupling between 4-bromobenzophenone (VIII) and methyl acrylate (IX) in the presence of palladium diacetate gave the unsaturated ester (X). Subsequent basic hydrolysis of the methyl ester group of (X) yielded p-benzoylcinnamic acid (XI). The title compound was then obtained by the coupling of acid (XI) with the precursor baccatin (VII) in the presence of EDC and DMAP.
