    Abstract: The present invention provides a method for inverting the 2’-hydroxy position of selected taxanes. The method includes protecting the 2’ hydroxyl group of a first selected taxane with a hydroxyl protecting group, such as a tosyl group, a mesyl group or a nosyl group. The protected taxane compound is then converted to an oxazole compound having an oxazole ring. The oxaxole ring is then opened by an appropriate process, such as by hydrolyzing the oxaxole compound thereby to form an intermediate compound, which is then converted to a second taxane. The intermediate compound may be an anime salt that is treated with a base to form the second taxane. The method contemplated by be used to convert 2’epi paclitaxel into paclitaxel. Alternatively, the method may be used to convert paclitaxel into 2’epi paclitaxel. The present invention also relates to novel compounds and intermediates formed by the process.
