Oxidation of taxol (1) or substituted taxols with Jones' reagent under appropriate conditions yielded 7-oxotaxol (6), 2',7'-dioxotaxol (9), or 2'-oxo-7-acetyltaxol (12).Treatment of 7-oxotaxol with DBU or silica gel yielded a D-secotaxol derivative 14.Hydrogenation of the 2'-acetate derivative of 14 yielded the unstable diketone 16, while hydrogenation of 14 itself followed by workup in methanol gave the lactone 17.
