A novel UV-mediated approach for the synthesis of previously unknown 3a,6a-dihydroxy-4-methyl-2,3,3a,6a-tetrahydro-6H-cyclopenta[b]furan-6-one derivatives from easily accessible substituted allomaltols containing a 2-aryl-2-hydroxyethyl fragment was elaborated. The suggested method is based on the ESIPT-promoted contraction of a 3-hydroxy-4-pyranone moiety followed by intramolecular trapping of a photogenerated α-hydroxy-1,2-diketone intermediate. For the first time, we have demonstrated that a side chain hydroxyl group can be employed for the concluding cyclization with a labile α-hydroxy-1,2-diketone fragment. The structure of one synthesized photoproduct was determined by X-ray diffraction.
