Abstract
A process for oxidizing cephalomannine and related taxanes in the presence of taxol is described. The process involves the use of ozone which is able to oxidize cephalomannine and easily oxidizable taxanes while leaving taxol essentially unchanged. Taxol can then be separated from the oxidized cephalomannine and other oxidized taxanes using conventional procedures. A process for oxidizing taxanes is also provided.
