PROCEDURES FOR THE PREPARATION OF COMBRETASTATINAS |
| abstract |
The invention relates to new methods of preparing combretastatins by Wittig condensation between nitromethoxybenzaldehyde and a trimethoxybenzyl phosphonium salt or conversely a nitromethoxybenzyl phosphonium salt with trimethoxybenzaldehyde or also by a Wittig reaction on the same derivatives, in which the nitro function has been reduced to an amino group. |
