Three new 7-deoxydocetaxel derivatives have been prepared from natural taxine B and isotaxine B: the first one, 2-debenzoyl-9-dihydro-1,2-O-benzylidene-9,10-O-isopropylidene-7-deoxydocetaxel has a slight cytotoxicity and a weak microtubule disassembly inhibitory activity; the other two derivatives, 9-dihydro-9,10-O-isopropylidene-7-deoxydocetaxel and 7-deoxy-10-acetyldocetaxel are cytotoxic and reveal
