摘要：

The photochemistry of enol esters 1 is dominated by electrocyclic ring opening (1b --> 3 + 4), 1,3-acyl migration (1c,d --> 6c,d) and [2 + 2] dimerization (1d --> 11). Photosensitization with triphenylpyrylium tetrafluoroborate (TPT) enhances formation of oxidation products (1b --> 5, 1c,d --> 9c,d + 10c,d), presumably through the intermediacy of radical cations 1b-d+.
