An intermolecular enantioselective photoreaction by a single‐crystal‐to‐single‐crystal transformation has been carried out for the first time, as is evident from X‐ray structure analysis and X‐ray powder diffractometric studies. This reaction, the dimerization of the title compound to cyclobutane derivative 1 (X=O, S), provides a good example for studying the mechanism of topochemical reactions in the crystal.
