PREPARATION OF TAXOL AND DOCETAXEL THROUGH PRIMARY AMINES

摘要

The invention relates to a process for converting Taxol A, B and C to Taxol primary amine which can then be easily and efficiently converted to Taxol A or docetaxel, thereby significantly increasing the yield of these products from biomass. The method includes the removal of the amide from the side-chain with Schwartz's reagent to form an imine, followed by the hydrolysis of the imine to the primary amine. The primary amine can then be converted to Taxol A or docetaxel. New Taxol imine compounds and primary amine salts have been formed by this process.
