Novel photosensitizers for the E/Z-isomerization of trienes. Part 1. Syntheses and application

Abstract

Uranine and its thioxanthene and selenoxanthene analogues, as well as the disodium salts of o-(6-hydroxy-3-oxo-3H-xanthen-9-yl)benzenesulphonic acid and its thioxanthene and selenoxanthene analogues, show different photosensitizer properties in the E/Z-isomerization of trienes. This has been verified by applying them to the technically useful conversion of tachysterol into previtamin D. The syntheses of the novel photosensitizers with thioxanthene and selenoxanthene moieties are also described.
