TWO-STAGE CONVERSION OF A PROTECTED TAXANESTER IN PACLITAXEL |
abstract |
The present invention relates to a method of producing paclitaxel from a protected coupled ester compound having formula (I), wherein P1 is a hydrogenatable protecting group, comprising the steps of deprotecting the 7-O-position, 3'-N-position and 2'-O-position thereof in the presence of an acid to form a first intermediate compound having formula (II), wherein HA is said acid, and benzoylating the first intermediate compound at the 3'-N-position thereby to produce paclitaxel. |
