Solid-state photocycloaddition reactions of 2-pyrones (1, 4) with benzophenone derivatives (2a-c, f) afforded highly site- and regioselective oxetanes (3a, 3b, 3c, 3f, 5a, 5b, 5c, 5f) across the C5-C6 double bond in 1 or 4 via the triplet excited state of 2. The site- and regioselectivities were explained by MO calculations.
