Conversion of 9-dihydro-13-acetylbaccatin III into 10-deacetylbaccatin III |
| abstract |
9-dihydro-13-acetylbaccatin III, one of the chemicals obtained from Taxus canadensis is used to produce, inter alia , 10-deacetylbaccatin III, a useful intermediate for the preparation of paclitaxel and analogues thereof. The 9-dihydro-13-acetylbaccatin III is converted into the 10-deacetylbaccatin III by a simple three-step process involving (a)replacement of the C-7 hydroxyl group of the 9-dihydro compound with a protecting group, (b)the oxidizing of the C-7 protected compound to produce a C-9 ketone, and (c)the deprotecting of the C-9 ketone to produce 10-deacetylbaccatin III. |
