Photochemical studies on bis-sulfide and -sulfone tethered polyenic derivatives
Résumé
This study focusses on the [2+2]-photocycloaddition of symmetric polyenic system tethered by an aryl bis-sulfide or sulfone platform. Using direct irradiation or photosensibilization, no expected ladderane product was isolated. In most cases, only tricyclic products including a single cyclobutane moeity were formed. Irradiation of bis-acrylic precursors in water with encapsulation by a host (cyclodextrin or cucurbituril) provided a stereoselective access to valuable cyclobutyl adducts.
