Abstract
A semi-synthesis of taxol using a protected baccatin III backbone which is esterified with a suitably protected side chain acid.
Claims
1. A process of producing paclitaxel from an intermediate compound having the general formula:
Formula (a)
wherein Pχ is a hydrogenatable benzyl protecting group comprising the steps of deprotecting and acylating the intermediate compound at the nitrogen position of the A-ring side chain to replace the CBZ protecting group with PhCO, deprotecting the side chain at the C-2' position to replace Pχ with H and deprotecting at C-7 to replace the TES protecting group with H.
2. The process of claim 1 wherein the step of deprotecting at C-7 occurs before the removal of the hydrogenatable C-2' benzyl protecting group.
3. The process of claim 2 wherein the step of deprotecting and acylating the side chain nitrogen occurs before the step of deprotecting at C-7.
4. The process of claim 2 wherein the step of deprotecting at C-7 occurs before the step of deprotecting and acylating the side chain nitrogen.
5. The process of claim 1 wherein the step of deprotecting and acylating the side chain nitrogen is accomplished by dissolving the compound of Formula (a) in isopropanol and thereafter adding Pearlman's catalyst under a hydrogen atmosphere for a first interval of time to form a first mixture and thereafter reducing said first mixture to residue and taking up said residue in a solvent, adding a tertiary amine base and thereafter adding benzoyl chloride.
6. The process of claim 5 wherein said solvent is selected from a group consisting of ethyl acetate and toluene.
7. The process of claim 5 wherein the tertiary amine base is triethylamine.
