  • Semi-Synthetic Conversion of Paclitaxel to Docetaxel
    Publication number: 20080051590
    Abstract: A process is provided for the semi-synthesis of taxane derivatives useful in the preparation of docetaxel, in particular, the semi-synthesis of protected taxane derivatives in a one pot reaction of protecting the C-2?, C-7 and C-10 positions and introducing a t-Boc group at the nitrogen of the amide group at the C-3? position in paclitaxel and subsequently conversion to docetaxel, and derivatives used therein.
