Fremgangsmåde til fremstilling af baccatin lll og derivater ud fra 10-deacetylbaccatin lll
10-Deacetylbaccatin III is selectively acylated to baccatin III and derivatives thereof in high yield with anhydrides (e.g. acetic anhydride), catalysed by Lewis acids. Extremely effective catalysts in this reaction are compounds of the formula MLx wherein M is a rare earth metal and L is a anion, p...

| description | 10-Deacetylbaccatin III is selectively acylated to baccatin III and derivatives thereof in high yield with anhydrides (e.g. acetic anhydride), catalysed by Lewis acids. Extremely effective catalysts in this reaction are compounds of the formula MLx wherein M is a rare earth metal and L is a anion, preferably a strong electron withdrawing counterion such as triflate. |
