摘要:
                                10-Deacetylbaccatin III 2 is a taxane diterpenoid isolated from the plant genus Taxus, which has been used for the partial synthesis of the antitumor compounds taxol and taxotere(R).  A number of structural modifications have been performed on 2 under acidic and basic conditions in order to obtain new synthetic precursors of taxol and taxotere(R) analogues.
