    • PROBLEM TO BE SOLVED: To provide a novel 13-ketobaccatin III, a taxane derivative and a method for production thereof.
      SOLUTION: The method for production of the taxane derivative includes functionalizing the 14-position of a 13-ketobaccatin derivative, and further converting into a compound of formula III (wherein X is -N
      3 , -NH
      2 , -NH-R
      3 , =CH-R
      8 , or -O-R
      3 when R
      6 is different from phenyl; R
      2 is hydrogen or acyl; R
      3 is 1-4C alkoxycarbonyl, or taken together with R
      4 to form carbonyl, thiocarbonyl, SO or SO
      2 ; R
      4 is hydrogen or taken together with R
      3 or R
      8 to form the groups specified in the respective definitions of R
      3 and R
      8 ; R
      5 is hydrogen or an alcohol-protecting group; R
      6 is aryl, substituted aryl, heteroaryl, with the proviso that it is different from phenyl when X is OR
      3 ; R
      8 is hydrogen, 1-4C alkyl, 1-4C alkoxycarbonyl, or taken together with R
      4 to form carbonyl; and R
      9 is acyl or hydroxyaminoacyl).
