A PROCESS FOR THE PURIFICATION OF 10-DEACETYLBACCATINE III FROM 10-DE ACET YL-2- DEBENZOYL-2-PENTENOYLBACCATINE III

摘要

A process for the preparation of 10-deacetyl-7,10-bis- trichloroacetylbaccatine III with HPLC purity higher than 99% and free from 2-debenzoyl-2-pentenoylbaccatine III by purification of 10-deacetyl-7,10-bis- trichloroacetylbaccatineIII followed by alkaline hydrolysis of the protecting groups in position 7 and 10.
