摘要:
The present invention relates to new intermediates for the semisynthesis of taxanes and their preparation processes. It relates to derivatives of oxazolidines or oxazolidinones, as well as to new derivatives of baccatine III. The general process for the synthesis of taxanes according to the invention enables to obtain a product such as PACLITAXEL in only five steps from products available in the market, compared to nine steps in general, for processes of the prior art.
摘要:
The present invention relates to novel intermediates for the hemisynthesis of taxanes and to their processes of preparation. The compounds of the present invention include precursor compounds of taxane side chains.
摘要:
New processes for the selective protection of the 7-position of 7,10-dihydroxytaxane derivatives, using &bgr;-substituted-alkoxycarbonyl groups which are more hindered than 2,2,2-trichloroethoxycarbonyl, and which are capable of being removed by a &bgr;-elimination mechanism, and the new intermediates resulting from these processes. The new intermediates of the invention are useful for preparing taxol and analogs thereof.
