合成路线1

该中间体在本合成路线中的序号：(I)

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：(VIII)

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.
