合成路线1
Selective protection of the 7-hydroxyl group of deacetylbaccatin (I) with triethylsilyl chloride provided silyl ether (II), which was acylated at position 10 with the activated ester (III) in the presence of lithium hexamethyldisilazide to give the benzoylcinnamic ester (IV). Further coupling of (IV) with beta-lactam (V) gave (VI), which by removal of the silyl groups with HF in pyridine-acetonitrile afforded (VII). The Boc group of (VII) was then removed with trifluoroacetic acid to give amine (VIII).

The Boc group of (VII) was then removed with trifluoroacetic acid to give amine (VIII). Then, benzoylation of the amino group of (VIII) provided benzamide (IX). Finally, hydrogenation of the cinnamyl double bond of (IX) in the presence of Wilkinson's catalyst furnished the target compound.
