The photochemical 6π‐electrocyclization of diarylethenes (DAE), 2‐vinylbiaryls (VBA) and their derivatives is widely used in organic synthesis. Combination of these motifs in one molecule opens the issue of selectivity of the photochemical reaction. We have found that upon UV irradiation, 3‐(1,2‐dia...
