Combretastatin preparation processes |
abstract |
"PREPARATION PROCESSES FOR COMBRETASTATINS". The present invention relates to novel processes of preparation of combrestatins by Wittig condensation between nitromethoxybenzaldehyde and a trimethoxybenzyl phosphonium salt or, conversely, a nitromethoxybenzyl phosphonium salt with trimethoxybenzaldehyde or a Wittig reaction thereon. derivatives whose nitro function was reduced in an amino group. |
