A process useful for the preparation of intermediates in synthesis or semi- synthesis of paclitaxel analogs wherein a starting taxane such as 10- deacetylbaccatin III is deacetylated at the C-4 position using a microorganism or an enzyme derived therefrom to provide 4-deacetyltaxanes, such as 4,10- dideacetylbaccatin III.
L'invention porte sur un procédé de préparation d'intermédiaires de synthèse ou de demi synthèse d'analogues de paclitaxel consistant à déacétyler un taxane tel que le 10-déacétylbaccatine III en position C-4 à l'aide de micro-organismes ou d'une enzyme en dérivant pour obtenir des 4-déacétyltaxanes tels que les 4,10-didéacétylbaccatine III.
