The stereoselectivity of the formation of macrocyclicstilbenes as well as the regioselectivity of their photocyclization are strongly influenced by the length of the connecting alkanediyl chain. The stereoisomers of the macrocyclicstilbenes and the corresponding diols are identified by chemical and spectroscopic means.
