isolated from the dried needles of Taxus baccata, was converted into six novel 7-deoxypaclitaxel analogs, 20, 21a,b, and 23-25, that have structural changes at C1, C2, and C4. A method for the introduction of the benzoyl function at C2, via a benzylideneacetal at C1-C2, will be revealed. All compounds showed very little or no measurable cytotoxic activity against some well-characterized human tumor
