Photochemistry of Cyclobutanes: Synthesis and Reactivity

“…This is observed in the reversible ring opening and ring closing of the dissymmetric cage compounds (Scheme 13) formed from substituted cyclopentadienones 318 . The synthesis of cage compounds related to this and others has been reviewed 319 . Irradiation of adducts 490 and 491 at 260 nm, where the benzenoid moiety absorbs, results in efficient (φ can be as high as 0.5) conversion to the corresponding naphthalene derivatives 320 .…”
