Abstract: The invention disclosed a total synthesis process of novel ethoxy combretastatins and their prodrugs. Combretastatins are chemically modified by ethoxy substituted on the 4'-position of their B aryl ring and are converted to be their soluble prodrugs of phosphate or their inner salt of phosphorylcholine by modifying the hydroxyl on the 3'-position of their B aryl ring. Similarly, 3'-amino combretastatin is 4'-ethoxy chemically modified and further side chain of amino acid can be introduced to the amino to form soluble prodrug of amino acidamide.  The structure of the said compound is showed as formula (I). Ethoxy combretastatins possess potent tubulin polymerization inhibitory activity and can be used for the treatment of inhibiting tumor or neovascular.  (see formula I)
