The regioselectivity of the intramolecular photocycloadditions of 1-Acyl-3-oxa-1,5-hexadienes appears, in general, to follow "rule of five" closure and give annelated 2-oxa-bicyclohexanes.
Intramolecular Photocycloaddition Reactions of 3-(2-Propenoxy)cyclopent-2-en-1-ones and 3-(2-Propenoxy)cyclohex-2-en-1-ones

The 3-oxy-1,5-hexadienones 4a, 4b, 5a, and 5b undergo intramolecular photocycloaddition reactions with quantum yields ranging from 0.2 to 0.002.In general, oxa substitution decreases the quantum yields and favors the formation of crossed closure pro
