You rang m′lord? Thermally induced successive ring openings of tris(alkoxytricyclobutabenzene) to hexaradialene are described. The isomerization reaction was highly stereoselective to afford a stereodefined hexaradialene 1 , given that the hydroxy groups on the four‐membered rings were protected by bulky substituents.
