PROCESS FOR PREPARING TAXOL DERIVATIVES AND CERTAIN INTERMEDIATE COMPOUNDS

摘要

The present invention relates to a novel process for preparing taxol derivatives, comprising a step of esterification of a baccatin III derivative with a carboxylic acid comprising an oxazolidine ring. A subject of the present invention is also certain novel intermediates involved in this process, and in particular the compound resulting from this esterification step. Said process can be carried out in order to prepare tesetaxel.
