A process for the preparation of compounds of the formula I DOLLAR F1 is described, in which R · 1 · H or (CH¶2¶) ¶m¶OH, R · 2 · H or (CH¶2¶) ¶n¶OH, R · 3 · H or (CH¶2¶) ¶p¶OH and m, n and p each independently represent 2 to 8. These compounds are advantageously suitable for use as a dietary supplement. They are also excellent for use in cosmetic formulations, e.g. B. as a UV filter. |
