METHOD FOR PRODUCING COMBRESTASTININS |
| abstract |
The present invention relates to new processes for the preparation of combretastatins by condensation using the Wittig method of nitromethoxybenzaldehyde and the phosphonium salt of trimethoxybenzyl or, conversely, the phosphonium salt of nitrometoxybenzyl and trimethoxybenzaldehyde or by the Wittig reaction between the same derivatives in which the nitro group is reduced to an amino group. .08. |
