摘要：

The proto-Photocycloadducts of methyl 2,4-dioxopentanoate to several methylene-cycloalkanes and -alkenes spontaneously caused retro-benzilic acid rearrangement, exclusively. The reaction proceeded quite cleanly, and a simple work-up without chromatographic separation allowed to isolate the products directly in very good material balance.
