我们开发了一种新的方法,利用13-酮衍生物(7)的C-4乙酰阴离子和各种烷基卤化物修饰10- deacetylbacaccatin III(5)的C-4位置。本文所建立的方法对于制备C-4修饰类taxoid类似物具有重要意义。
We have developed a new method to modify the C-4 position of 10-deacetylbaccatin III (5) using the C-4 acetoxy anion of the 13-keto derivative (7) and various alkyl halides. The method developed herein should be very useful for the preparation of C-4 modified taxoid analogs.
