<p>A method for preparing 13α-cinnamoyl baccatine III or 10-deacetyl baccatine III of formula (I) by condensation of a mixed anhydride having general formula (II) on a derivative of baccatine III or 10-deacetyl baccatine III of general formula (III). In formulae (I) and (III), R1 is an acetyl or trichloro-2,2,2-ethoxycarbonyl radical. In formula (II), R stands for 1-5 substituents which are the same or different (halogen, nitro, methyl, methoxy).</p> |
