A general synthetic route for the Pd-catalyzed cross-coupling of an arylzinc reagent with arylvinyl iodides (Negishicross-coupling) has been developed. The system permits efficient and selective preparation of E-stilbenes and their analogues. It also functions effectively at low levels of catalyst loading without the need for an additional ligand and tolerates a wide range of functional groups including
The present invention relates to Stilbene derivatives of the general formula I or a pharmaceutically acceptable salt thereof have properties such as high water solubility, bioavailability and effective as carcinostatics.
