Abstract | 5,15-Diphenylporphyrin was regiospecifically halogenated in high yield to give 5-iodo-15-bromo-10.20-diphenylporphyrin, which was then subjected to Heck and Stille-type coupling reactions to form unsymmetrically substituted porphyrins. The regioselectivity of the iodination of diphenylporphyrins and subsequent formation of amphiphilic porphyrins via palladium-based methodology was also studied. The utility of this method for the synthesis of photodynamic sensitisers has been demonstrated on AR4-2J rat pancreatic carcinoma cells. Copyright (C) 2000 John Wiley & Sons, Ltd. |
