Description

The method of a kind of synthesizing cis-stilbene derivative and phosphate disodium salt predrug thereof
Technical field
It is synthetic to the present invention relates to compound, relates in particular to the high-efficiency synthesis method that tumor vascular targeting destroys the medicine cis-stilbene derivative.
Background technology
CombretastatinA-1 and A-4 (being abbreviated as CA-1 and CA-4) are tubulin growth inhibitor (pettit G R, SinghSB, Can.J.Chem. (1987) 652390-2396).
Though the discovery time of Combretastatins compounds is not long, but cause extensive studies interest.Current research shows that this class cis-stilbene derivative has the tumor vascular targeting destruction, and they are the new type antineoplastic medicines that have potentiality.
The committed step of synthetic this compounds is the Wittig reaction.To destroy the factor be cis-configuration to diphenylethylene the most effective unitary tumor vessel in Combretastatin, and the diphenylethylene compounds of transconfiguration is to very little of tumor vessel destruction.So in the complete synthesis process of this compounds, improve the stereoselectivity of Wittig reaction, increase the ratio of cis-isomeride, be to improve a crucial step of the efficient synthetic of productive rate.
Professor Pettit at first uses isovanillin and 3,4, and the 5-TMB is that raw material is through the synthetic CA-4 (J.Med.Chem of five steps reaction, 1995,38:1666), its ratio is Z/E=3/2, then, the method by column chromatography obtains purity greater than 98% CA-4, and overall yield is generally less than 30%.Calendar year 2001 OXigeneINC has proposed 3 hydroxyls with trityl chloride protection isovanillin, and with 3,4,5-trimethoxyphenyl methylene radical triphen base Phosphonium carries out the wittig reaction, sloughs trityl as protecting group then, thus synthetic CA-4 (WOO206279Al).To 3:1, overall yield is about 37% at 3:2 for the ratio of Z formula and E formula isomer.
In clinical use, CA-4 need be transformed into its disodic alkaliine water-soluble prodrug.Professor Pettit implements phosphating reaction (US4,996,237) with tetracol phenixin and dibenzyl phosphite.OxigeneINC company utilization carbon tetrabromide and dibenzyl phosphite carry out phosphating reaction (WOO206279Al).As everyone knows, tetracol phenixin is the very big chemical reagent of a kind of toxicity.
Therefore, this area presses for the high synthetic method of ratio that a kind of productive rate height and resulting CA-4Z formula and E formula isomer are provided.Simultaneously, this area also presses for provides a kind of easy and avoid using the method for synthesizing cis-stilbene derivative phosphate disodium salt predrug of the tetracol phenixin kind solvent of high poison.
