    • This invention relates to a method for preparing taxane derivatives of general formula (I) by esterification at a temperature between −10 and 60° C. of a derivative of baccatine III or 10-deacetyl baccatine III of general formula (II) by means of an acid of general formula (III), followed by replacement of the protective groupings G1, G2 and R2 of the resulting product by hydrogen atoms. In formulae (I), (II) or (III), Ar stands for an aryl radical; R stands for hydrogen or acetyl; R1 is benzoyl or ter.butoxycarbonyl; G1 is a hydroxy function protective grouping, G2 stands for the acetyl radical or a hydroxy function protective grouping, and R2 stands for a hydroxy function protective grouping.
    • 本发明涉及通过式(I)的紫杉烷衍生物的制备方法,其通过在-10至60℃的温度下通过式(II)的杆菌肽III或10-脱乙酰杆菌肽III的衍生物通过在 通式(III)的酸,然后用氢原子代替所得产物的保护基团G1,G2和R2。 在式(I),(II)或(III)中,Ar表示芳基; R代表氢或乙酰基; R1是苯甲酰基或叔丁氧基羰基; G1是羟基功能保护性分组,G2代表乙酰基或羟基功能保护性分组,R2代表羟基功能保护性分组。
