Enlightning synthesis: A light‐induced intramolecular [2+2] photocycloaddition reaction (1→2) was the key step in the stereoselective synthesis of (+)‐lactiflorin (3) and its triacetate. By comparison with reported analytical data, it was possible to unambiguously elucidate the structure of this natural product, to which three different structures had been previously assigned.
