Abstract
Sensitized irradiation (λ = 254 nm) of the title compounds 2 a and 2 b in benzene affords the tetracyclic oxetanes 3 a and 3 b. The irradiation of 2 c under similar conditions yields equal amounts of 3 c and the cyclopentadiene derivative 5. The formation of the photoproducts is discussed.
