Photoreactions of Semi-Stiff-Diarylethenes Based on the Cyclohexenol Motif

Nonsymmetric diarylethenes with an additional "stiff" cyclohexenol ring undergo various types of tandem transformations launched by light-induced 6π-photocyclization. Among these, there are two novel reactions (formal [1,3]-H migration and complete aromatization to an anthracene derivative) as well as photorearrangement and formal methane elimination. This diverse reactivity demonstrates the great potential of
