dc.description.abstractThe natural product cephalomannine can be converted to the important anticancer natural product taxol by a simple process involving the steps of dihydroxylation to give cephalomannine-diols, diol cleavage, benzoylation at the 2'-position and reaction with a 1,2-diamine. The same process when applied to mixtures of taxol and cephalomannine makes it possible to separate taxol from cephalomannine-diols by simple flash-chromatography after the dihydroxylation step. If the benzoylation step is avoided in the above sequence of conversions, the process leads to the free amine (N-debenzoyltaxol). In addition, the selection of an acylating reagent other than that with the benzoyl group for acylation of the free amine (N-debenzoyltaxol), allows the preparation of taxol analogs with other N-acyl substituents.en
