Abstract
Abstract A taxane derivative of the formula ##STR1## wherein R 1 is phenyl or substituted phenyl, R 3 is CH 3 O--, or CH 3 CH 2 O--, Z is --OT 1 , T 1 is hydrogen, hydroxyl protecting group, or --COT 2 . T 2 is H, C 1 -C 6 alkyl, C 1 -C 6 alkenyl, C 1 -C 6 alkynyl or monocylic aryl, Ac is acetyl, and E 1 and E 2 are independently selected from hydrogen and functional groups which increase the water solubility of the taxane derivative are useful as antitumor agents.
