Title:
SEMI-SYNTHETIC CONVERSION OF PACLITAXEL TO DOCETAXEL
Document Type and Number:
WIPO Patent Application WO2006004898
Kind Code:
A3
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 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.
