Abstract

L'invention concerne un procédé permettant de préparer du Taxol et des analogues du Taxol, ainsi que leurs intermédiaires. Selon le procédé, on protège le groupe hydroxy en C7 de la 9-dihydro-13-acétylbaccatine III par un groupe protecteur approprié; on oxyde le groupe hydroxy en C9; et on ajoute un chaîne latérale appropriée en position C13. Parmi les intermédiaires, on trouve un composé de formule (1), dans laquelle R est choisi dans le groupe comprenant benzyle, benzyle substitué, benzylformate, benzylformate substitué, tosyle, tosyle substitué, dihydropyrane, méthoxyméthyle, benzoyle et benzoyle substitué.
