METHOD FOR PREPARING DOCETAXEL

摘要

The invention concerns a method for preparing docetaxel from paclitaxel, including the following steps: a) deacylating paclitaxel, b) protecting the free hydroxy functions, in 7-, 10- and 2'-position respectively, c) debenzoylating the amine in 3'-position, into a primary amine derived for 10-deacetylbaccatine whereof the hydroxy functions in 7-, 10- and 2'-position are protected, d) functionalizing the amine with a t-butoxycarbonyl radical to obtain a docetaxel derivative of general formula (I), wherein: X represents protecting radicals or hydrogen atoms, then, if required, e) releasing the initially protected hydroxy functions to obtain docetaxel.
